Chapter 1, Problem 68SGR

To determine

To find: $g\left(2\right)$ if the functionsare $f\left(x\right)=2x+4$ and $g\left(x\right)=x^2-3$ .

Answer to Problem 68SGR

The function value $g\left(2\right)$ is $1$ .

Explanation of Solution

Given:

The functions are $f\left(x\right)=2x+4$ and $g\left(x\right)=x^2-3$ .

Calculation:

The value of function $g\left(2\right)$ is calculated as follows:

  $\begin{array}{c}g\left(2\right)={\left(2\right)}^2-3\\ =4-3\\ =1\end{array}$

Thus, the function value $g\left(2\right)$ is $1$ .
