Answer 1

Answer:

Umm, I believe your only correct answer for your equation above would be -1.

Step-by-step explanation:

Using the PEDMAS method:

-2 - 3= -5

= -5 - (-4)

-(-4) = 4

= -5 + 4

-5 + 4 = -1

So, your answer would be -1. Hope this helps!

Use the graph of f to find F(2).

A. 0.5
B. Does not exist
C. -8
D. -0.5

Answers

Hey there! Before we start with the problem, you mean f(2) instead of F(2) if I'm correct. In maths, variables are case-sentitive so F and f both are different.

First, f(2) means the value of y at x = 2.

f(2) is when we substitute x = 2 in and receive the output (y-value).

In coordinate plane, we have (x,y) as a point. What we have to do is to look at the graph, you will see the point that contains (2,-8)

That's it! Refer above, f(2) is when we substitute x = 2 and get y-value.

Hence, f(2) = -8

Let me know if you have any questions!

A is 3/4

B is 2/3

C is 9/10
