Chapter 7.6, Problem 54PPS

To determine

To find a match to the given graph with the given list of functions

Answer to Problem 54PPS

  $n(x)=5f(x)$

Explanation of Solution

Given:

  

Also, the parent functions: $f(x)={\left(\frac{3}{2}\right)}^x$

Calculation:

Let,

  $\begin{array}{l}\Rightarrow y=nf(x)\\ \Rightarrow y=n{\left(\frac{3}{2}\right)}^x\mathrm{....................}(i)\end{array}$

Where n is constant.

Now, equation ( i ) is compared with the list of functions given.

The above format matches only one function which is:

  $n(x)=5f(x)\Rightarrow n(x)=5{\left(\frac{3}{2}\right)}^x$

Verification:

Using graphing utility tool, the graph is plotted and compared with the given graph.

(i(ii

Interpretation:

When both the above graphs are compared it is clear that they are same, which means the calculations done is correct.

Conclusion:

Hence, the function for the given graph is $n(x)=5f(x)$ .
