Chapter 1.7, Problem 15CYU

To determine

To find: $g\left(a\right)+9$if the function is $g\left(x\right)=x^2-4$ .

Answer to Problem 15CYU

The function value $g\left(a\right)+9$ is $a^2+5$ .

Explanation of Solution

Given:

The function is $g\left(x\right)=x^2-4$ .

Calculation:

The function $g\left(a\right)+9$ is calculated as follows:

  $\begin{array}{c}g\left(a\right)+9={\left(a\right)}^2-4+9\\ =a^2+5\end{array}$

Thus, the function value $g\left(a\right)+9$ is $a^2+5$ .
