Question

Please help, thank you!!

Answer 1

D (4)

Explanation:

So we have the function:

`f(t)=3t^2+5t+6`

And we want to find f(-3).

To do so, substitute -3 for x. Thus:

`f(-3)=3(-3)^2+5(-3)+6`

Square:

`f(-3)=3(9)+5(-3)+6`

Multiply:

`f(-3)=27-15+6`

Add:

`f(-3)=18`

So, our answer is D (4)
