Question

If g(x)=x^2+3, find g(4)

Answer 1

g(4)=19

Explanation:

We want to find what g(x), or y is, when x is equal to 4.

Therefore, we can substitute 4 in for x in the equation

g(x)=x^2+3

g(4)=4^2+3

Evaluate the exponent first

g(4)=16+3

Add

g(4)=19

Answer 2

g(4)=19

Explanation:

Plug 4 in for x:

4^2+3=16+3=19

Therefore, g(4)=19
