Question

If f(x)=4x^2-6

find f(3)

Answer 1

Answer: f(3) = 30

Explanation:

Answer 2

f(3) = 30

Explanation:

f(x) = 4x² - 6

To find f(3) substitute the value of x that's 3 into f (x) that is for every x in f (x) replace it with 3

We have

f(3) = 4(3)² - 6

= 4(9) - 6

= 36 - 6

We have the final answer as

f(3) = 30
