Chapter 8, Problem 21CR

To determine

To find:

The value of $g(x)$ , when $x=4$ .

Answer to Problem 21CR

The value of $g(x)$ , when $x=4$ would be $-2$ .

Explanation of Solution

Given:

A function:

  $g(x)=-2x+6$

Calculation:

To find the value of $g(x)$ , when $x=4$ , we will substitute $x=4$ in our given function as shown below:

  $\begin{array}{l}g(x)=-2x+6\left(\text{Given function}\right)\\ g(4)=-2(4)+6\left(\text{Substituting }x=4\right)\\ g(4)=-8+6\\ g(4)=-2\end{array}$

Therefore, the value of $g(x)$ , when $x=4$ would be $-2$ .
