Question

Evaluate the function for the given value.

f(-3) if f(x) = 4x^2 + 7

Answer 1

f(-3) = 43

Explanation:

f(x) = 4x² + 7

To find f(-3) substitute the value of x that's - 3 into f (x) that's replace every x in f (x) by - 3

We have

f(-3) = 4(-3)² + 7

= 4(9) + 7

= 36 + 7

We have the final answer as

f(-3) = 43
