Question

Evaluate the function.
f(x) = 2x2 – 15
Find f(-2)

Answer 1

Answer:

$f(-2)=-17$

Step-by-step explanation:

$f(-2)=2(-2)^2-25\\\\f(-2)=2(4)-25\\\\f(-2)=8-25\\\\f(-2)=-17$

Answer 2

f(x) = 2x² - 15

f(-2) = ?

Substitute -2 in the place of x.

f(x) = 2x² - 15

f(-2) = 2(-2)² - 15

f(-2) = 8 - 15

f(-2) = -7
