Question

Find f(2) for f(x)=3x2+9x−6

.
Select one:
a. f(2) = 24
b. f(2) = 48
c. f(2) = -12

Answer 1

a.
`f(2)=24`

Explanation:

Given function:

`f(x)=3x^2+9x-6`

To find
`f(2)`

Solution:

In order to find
`f(2)`,we need to plugin input=2 i.e. the value of
`x=2` in the function and find the output by evaluating.

Plugging in
`x=2` in the given function.

`f(2)=3(2)^2+9(2)-6`

Evaluating.

`f(2)=3(4)+18-6`

`f(2)=12+18-6`

∴
`f(2)=24` (Answer)
