### Determine whether the given function is linear, exponential, or neither. For those that are linear functions, find a linear function that models the data. for those that are exponential, find an exponential function that models the data. $\begin{array}{}x& \text{g(x)}\\ \text{−1−1}& \text{3}\\ \text{0}& \text{6}\\ \text{1}& \text{12}\\ \text{2}& \text{18}\\ \text{3}& \text{30}\end{array}$

When you are looking for exponential function questions and answers, there are at least six transformations that you must use. Some examples with detailed solutions can be found below. Think about exponential function questions to see what approaches have been used, depending on what question has been asked. It will help you to understand the way things can be explained either in words or with a help of a graph. Start with an exponential model equation and proceed from there by using samples. There are also exponential growth questions that will be helpful as you learn.
