What are the domain and range of this function?
===========================================
Explanation:
The domain is the set of allowed x inputs. We can plug in any x value we want as the graph stretches on forever to the left and to the right. There aren't any division by zero errors or any issues like that to worry about, so that's why we don't kick out any x values from the domain.
The domain being all real numbers translates to the interval notation [tex](-\infty, \infty)[/tex] which is basically saying [tex]-\infty < x < \infty[/tex]
-----------------------------------
The range is the set of y outputs possible. The graph shows that y = 1 is the smallest y output, so y = 1 or y can be greater than this.
In short, [tex]y \ge 1[/tex] is the range which converts to the interval notation [tex][1, \infty)[/tex] which is the same as saying [tex]1 \le y < \infty[/tex]
-----------------------------------

The equation of this absolute value function is y = |x|+1
HELP PLEASEEEEEEEEEEEEEEEEEEEEEEEEE
Answer:
The solution set to the absolute value is:
[tex]S = \{x \in \mathbb{R}| x \ge 0\}[/tex] or [tex]S = [0, +\infty)[/tex]
Negative real numbers are not included in the solution set, as for [tex]x < 0[/tex], [tex]|x| = - x[/tex].
Step-by-step explanation:
From Mathematics, we know that absolute values are defined by the following characteristics:
1) For [tex]x \ge 0[/tex], [tex]|x| = x[/tex]
2) For [tex]x < 0[/tex], [tex]|x| = - x[/tex]
Then, if [tex]|x| = x[/tex], then the solution set to the absolute value is:
[tex]S = \{x \in \mathbb{R}| x \ge 0\}[/tex] or [tex]S = [0, +\infty)[/tex]
Negative real numbers are not included in the solution set, as for [tex]x < 0[/tex], [tex]|x| = - x[/tex].
WHAT IS THIS HELP- 20 points i think-
Answer:
(6,5)
Step-by-step explanation:
To keep the sides parallel, the y coordinate must be the same as the top point so y = 5
The distance between the bottom points is 1, so the distance between the top points must be 1
The point could be at 5-1 =4 or 5+1 = 6
(4,5) or (6,5)

If a 32-gram serving of pasta contains 4g of protein, how many grams of protein are in a 908-gram box of the pasta ?
Step-by-step explanation:
This is my solution you honestly just need to cross multiply
Answer:
113.5
Step-by-step explanation:
32 : 4 = 908 : X
X = (4 * 908) / 32
X = 113.5
Given that ABCD is a rectangle, find the perimeter of the figure below. Round your answer to the nearest tenth. *
Options
18 ft
19.7 ft
21 ft
24.4 ft
9514 1404 393
Answer:
(b) 19.7 ft
Step-by-step explanation:
The perimeter of the figure is the sum of the lengths of the 3 straight sides and half the circumference of a 3-ft circle.
P = 6 + 3 + 6 + (1/2)(π)(3) = 15 +3/2π ≈ 19.712 . . . feet
The perimeter is about 19.7 feet.
Leigh plans to estimate the area of the figure on the grid by identifying the full and partial squares that make up the figure.
If PQ = 4i+3j+2k, find /PQ/
Answer:
| PQ | = [tex]\sqrt{29}[/tex]
Step-by-step explanation:
Given
PQ = ai + bj + ck , then
| PQ | = [tex]\sqrt{a^2+b^2+c^2}[/tex]
Here PQ = 4i + 3j + 2k , then
| PQ | = [tex]\sqrt{4^2+3^2+2^2}[/tex] = [tex]\sqrt{16+9+4}[/tex] = [tex]\sqrt{29}[/tex]

what number is exactly halfway between 2.5 and 3.5
Answer:
3 is exactly halfway between 2.5 and 3.5.
Step-by-step explanation:
The first number is 2.5
The second number is 3.5
We need to find the number that is exactly halfway between 2.5 and 3.5. It can be calculated as follows :
[tex]n=\dfrac{2.5+3.5}{2}\\\\n=\dfrac{6}{2}\\\\n=3[/tex]
Hence, 3 is exactly halfway between 2.5 and 3.5.
What is the equation of a circle with center (4, 4) and radius 7?
Answer:
(x-4)^2 + (y-4)^2 = 49
Step-by-step explanation:
The equation of a circle is given by
(x-h)^2 + (y-k)^2 = r^2 where ( h,k) is the center and r is the radius
(x-4)^2 + (y-4)^2 = 7^2
(x-4)^2 + (y-4)^2 = 49

Rewrite [tex]sin^25xcos^25x[/tex] simplified using power reduced formulas
Step-by-step explanation:
The power reducing formulas are given by the following:
[tex]\sin^2 x = \dfrac{1- \cos2x}{2}[/tex]
[tex]\cos^2 x = \dfrac{1+ \cos2x}{2}[/tex]
We can then write the given expression as
[tex]\sin^25x \cos^25x[/tex]
[tex]= \left(\dfrac{1- \cos 2(5x)}{2} \right) \left(\dfrac{1+ \cos 2(5x)}{2} \right)[/tex]
[tex]= \dfrac{1}{4}(1- \cos 10x)(1+ \cos 10x)[/tex]
[tex]= \dfrac{1}{4}(1- \cos^2 10x)[/tex]
[tex]= \dfrac{1}{4} \left(\dfrac{1- \cos 20x}{2} \right)[/tex]
or
[tex]\sin^25x \cos^25x= \dfrac{1}{8}(1- \cos 20x)[/tex]

Rammone invests R505 050.00 for three years at a banking institution when
will grow at 5% compound interest per year.
2.2.1
Use a yearly STEP by STEP or a long method and calculate the
interest earned after three years. (Do not use the compound intere
formula.)
Answer:
RM79 608.51
Step-by-step explanation:
First year,
RM505 050.00×5%=RM505 050.00×5/100
=RM25 252.50
second year,
(RM505 050.00+RM25 252.50)×5%=RM530 302.50×5/100
=RM26 515.13
third year,
(RM530 302.50+RM26 515.13)×5%=RM556817.63×5/100
=RM27840.88
three years interest,
RM25 252.50+RM26 515.13+RM27840.88=RM79608.51
I don't know that is R or RM
if it is R ,sorry

Max has 4/5 qt of apple juice. He drinks 1/2 qt of it. How many apple juice does he have left? (Give your answer in quarts)
Answer:
3/10 quarts.
Step-by-step explanation:
Set the denominators equal to one another.
4/5 = 8/10 (multiplied by a factor of 2)
1/2 = 5/10 (multiplied by a factor of 5)
Subtract the 5/10 from the 8/10
3/10 qt
