Question

I don’t understand at all

Answer 1

26

Explanation:

Ok first u find f(2) so for that u have to input 2 into the value of x. So 2^2 +1 =5

When we get 5 we input THAT into f(x)

So:

F(5) = 5^2 +1

=26

Answer 2

26

Explanation:

It says find f(f(2)), so we need to find f(2) and then input that into the same function. f(2)=5 so then we input that into the function again and get 26. Boom.
