Question

If f(x)=2^2+2,findf(5)

Answer 1

f(5)=52

Step-by-step explanation

The given function is

`f(x) = 2 {x}^(2) + 2`

We substitute x=5 to obtain;

`f(5) = 2 {(5)}^(2) + 2`

We evaluate the exponent to obtain:

`f(5) = 2 (25) + 2`

We multiply out to get:

`f(5) = 50 + 2`

We now simplify to get:

`f(5) = 52`
