Question

Evaluate the following expressions given the functions below.f(x) = 2x – 5 g(x) = x² + 3 h(x) = –2 +4MathMLXQuestion 1(1 point)g(2)=

Answer 1

Since the exercise is regarding the g function, we will only be using this function.

$g(x)=x^2\text{ + 3}$

g(2) means that we will be replacing the x variable in the equation by 2.

We get,

$g(x)=x^2\text{ + 3}$$g(2)=2^2\text{ + 3}$$g(2)=4\text{ + 3}$$g(2)=7$

Therefore, g(2) = 7.
