Question

Find f(2) if f(x)=(x+1)^2

Answer 1

f(x) = 9

Explanation:

You know that x is equal to 2 because f(2) was originally f(x).

Now you know that x is and so you substitute x for 2

2 + 1 is 3 and 3 and 3 * 3 because the exponent is 2 is 9

Answer 2

9

Explanation:

f(2), if f(x)=(x+1)^2

x=2

(2+1)^2

3^2=3x3

=9
