Chapter 1, Problem 12SGA

To determine

To find: $g\left(2\right)$

Answer to Problem 12SGA

3

Explanation of Solution

Given information:

  $g\left(x\right)=7-x^2$

Calculation:

Put $x=2$ in $g\left(x\right)$ and evaluated as follows:

  $\begin{array}{c}g\left(x\right)=7-x^2\\ g\left(2\right)=7-{\left(2\right)}^2\\ =7-4\\ =3\end{array}$

Thus, the value of $g\left(2\right)$ is 3.
