The answer to your question is: -3

Step-by-step explanation:

I think this is a very simple question, the only thing that you have to do is to look for -2 in the x-axis and after that you go downwards until you find the line or curve.

In the graph we find two values for x equal to -2, these values are -3 and -4.

But for -3 we have a dark blue point this means that this point is part of the function while for -4 we have just the contour of the circle this means that this point is not part of the function.

So, the only possible answer is f(-2) = -3

option 3 . (5x + 1) - (-10x + 6)

step-by-step explanation:

option 1 :

(4x + 3) + (-9x + 4)

or 4x+3 -9x + 4

or -5x + 7

option 2

(x - 2) - (6x - 9)

or x-2-6x + 9

or -5x + 7

option 3

(5x+ + 6)

or 5x + 1 + 10x -6

or 15x -5

option 4

-4x+2x+7-3x

-7x + 2x + 7

-5x + 7

hence only option 3 did   not satisfy the given simplify expression.
