Describe how each graph is obtained from the graph of y= f(x).

(a) y = f(x – 2)

Can somebody help telling what does it mean? what does it want us to do? ​

Answers

Answer:

see explanation

Step-by-step explanation:

Give the graph of y = f(x) then y = f(x + a) represents a horizontal translation of y = f(x)

• If x > 0 then a shift to the left of a units

• If x < 0 then a shift to the right of a units

Thus

y = f(x - 2) is the graph of y = f(x) translated 2 units right

-18, -9, 18, or 9​

Answers

Answer:-18

Step-by-step explanation:

6(x−3)+x=7x−18

Step 1: Simplify both sides of the equation.

6(x−3)+x=7x−18

(6)(x)+(6)(−3)+x=7x+−18(Distribute)

6x+−18+x=7x+−18

(6x+x)+(−18)=7x−18(Combine Like Terms)

7x+−18=7x−18

7x−18=7x−18

Step 2: Subtract 7x from both sides.

7x−18−7x=7x−18−7x

−18=−18

Step 3: Add 18 to both sides.

−18+18=−18+18

what do you call a crushed angle ?

Answers

Answer:

A Rectangle

Step-by-step explanation:

a wrecked angle

A crushed angle is commonly referred to as a "rectangle" or a "wrecked angle".

When an angle is crushed or collapsed, its sides are no longer straight or evenly spaced, and its vertex may be shifted or deformed.

This deformation can occur in various contexts, such as in physical objects or in mathematical diagrams. The angle's original shape has been significantly changed due to external influences.

Thus, a crushed angle is commonly referred to as a "rectangle" or a "wrecked angle".

This is a play on words, as a rectangle is a shape with four right angles, and when an angle is crushed or wrecked, it can resemble a rectangle.
