Question

if x= -3, then f(x)=4²+8x-15 evaluate the equation

Answer 1

GIVEN EQUATION :-

=> f(x) = 4² + 8x - 15
_________________

Putting "X = -3" in given equation, we get

=> f(x) = 4² + 8x - 15

=> f(-3) = 4² + 8(-3) - 15

=> f(-3) = 16 -24 -15

=> f(-3) = 16 - 39

=> f(-3) = -23
____________[ANSWER]

Answer 2

answer is - 23 if x=-3
