The answer is D. -2x+5.
If we simplify the left side of the equation first given, we come to the expression -2x-10.
If we solve for D., we get the same results. Thus, because an equation with all the same variable terms and constants have infinite solutions, the answer is D.
Hope this helps!

Answer:
f(-2) = 5
Step-by-step explanation:
To find f(-2), plug in -2 wherever there is an x.
f(x) = 4x² + 3x - 5
f(-2) = 4(-2)² + 3(-2) - 5
f(-2) = 4(4) + 3(-2) - 5
f(-2) = 16 - 6 - 5
f(-2) = 10 - 5
f(-2) = 5
