Question

Given the function f(x) = 8x2 -14x - 10, find f(-2)

Answer 1

-32 I think (plz dont be mad at me if this is wrong)

Explanation:

Answer 2

f(-2) = 50

Explanation:

f(x) = 8x^2 - 14x - 10, find f(-2)

Just like how -2 replaced x in f(x), you will replace x with -2 in the equation

f(-2) = 8(-2)^2 - 14(-2) - 10

f(-2) = 8(4) + 28 - 10

f(-2) = 32 + 18

f(-2) = 50
