Chapter 4, Problem 22CR

To determine

To find:The value of the function $h(x)=-4x+61$ for $x=2$ and $x=7$ .

Answer to Problem 22CR

  $\begin{array}{l}h(2)=53\\ h(7)=33\end{array}$

Explanation of Solution

Given information: $h(x)=-4x+61$

Calculation:

Putting $x=2$ in $h(x)=-4x+61$ ,

  $\begin{array}{l}h(2)=-4(2)+61\\ \Rightarrow h(2)=-8+61\\ \Rightarrow h(2)=53\end{array}$

Putting $x=7$ in $h(x)=-4x+61$ ,

  $\begin{array}{l}h(7)=-4(7)+61\\ \Rightarrow h(7)=-28+61\\ \Rightarrow h(7)=33\end{array}$

Thus, the value of $h(x)=-4x+61$ for $x=2$ is 53 and for $x=7$ is 33.
