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

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

-0.5

Step-by-step explanation:

f = y

f(2) is just basically say y = 2, so you look for the ordered pair that has positive 2 in the y values, then just find x.

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
