Question

If g(x) = x^2 + 3, find g(4). A.8 B.11 C.19 D.16

Answer 1

C

Explanation:

So we have the function:

`g(x)=x^2+3`

And we want to find g(4).

To do so, substitute 4 into x for g(x). In other words:

`g(4)=(4)^2+3`

Now, we simply need to evaluate.

4 squared is 16:

`g(4)=16+3`

Add:

`g(4)=19`

So, g(4) is 19.

Our answer is C.

And we're done!
