Question

Given the function f(x) = x2 + 8x – 12, what is the
value of f(2)?

Answer 1

`f(x) = {x}^(2) + 8x - 12 \\ f(2) = (2)^(2) + 8(2) - 12 \\ = 4 + 16 - 12 \\ f(2) = 8`

I hope I helped you^_^

Answer 2

f(2) = 8

Explanation:

f(x) = x^2 + 8x – 12

Let x = 2

f(2) = 2^2 + 8*2 – 12

= 4 + 16 -12

=20-12

= 8
