Answer:
C
Step-by-step explanation:
So we have the function:
[tex]g(x)=x^2+3[/tex]
And we want to find g(4).
To do so, substitute 4 into x for g(x). In other words:
[tex]g(4)=(4)^2+3[/tex]
Now, we simply need to evaluate.
4 squared is 16:
[tex]g(4)=16+3[/tex]
Add:
[tex]g(4)=19[/tex]
So, g(4) is 19.
Our answer is C.
And we're done!
