For the following exercises, simplify the expression. $\left(\frac{a^{2}}{b^{3}}\right)^{4}$

Matt decides whether a linear function generated Table D. Matt reasons, "Each output is two more than the previous output, so the function must be linear, but I can't make any rule work. For Instance, f(x)=2x+1 works for the first few inputs, but it doesn't work for inputs 4 or 7. Table D

$$\begin{array}{|c|c|} \hline \text { Input, } x & \text { Output, } f(x) \\ \hline 0 & 1 \\ \hline 1 & 3 \\ \hline 2 & 5 \\ \hline 4 & 7 \\ \hline 7 & 9 \\ \hline \end{array}$$

a. What is Matt doing wrong? Explain. b. Use plotted points or a diagram to show that the table does not match a linear function.
