Question

The table below represents an exponential function what is the common ratio

Answer 1

Given:

A table representing an exponential function.

The x-values represent the terms, while the y-values represent the numbers.

The common ratio is gotten from the numbers (y-values).

The formula for common ratio is given by;

`\begin{gathered} r=\frac{present\text{ term}}{preceed\text{ ing term}} \\ \\ \text{Hence,} \\ r=(108)/(36)=(36)/(12)=(12)/(4)=(4)/(1.33\ldots)=(1.33\ldots.)/(0.44\ldots) \\ r=3 \end{gathered}`

Therefore, the common ratio is 3.
