Respuesta :

when you replace x with 4 you get g(4)=4^2 +3 you get 16 +3 and then when you add those you get 19

Answer:

g(4) = 19.

Step-by-step explanation:

Given : If g(x) = x² + 3.

To find :  find g(4)

Solution : We have given that g(x) = x² + 3.

We need to find g(4)

Plug the vale of x = 4

g(4) =  (4)² + 3.

g(4) = 16 +3.

g(4) = 19.

Therefore,  g(4) = 19.
