Question

The graphs of four exponential functions are shown below:

(attacked below)

Which pair of graphs should be plotted to show the solution to (equation below w/ graph)

Answer 1

\[4(2)^x = 4\left(\begin{matrix}1 \\ 2\end{matrix}\right)^x\]

Answer 2

Put x = 0, What is the y-value of \(4(2)^x\) and \(4\left(\frac 12\right)^x\) ?

Answer 3

4 = 4

Answer 4

Does that mean A to B? @aum

Answer 5

Yes. A and B. B is the increasing function and it represents \(4(2)^x\).
A is a decreasing function and represents \(4\left(\frac 12\right)^x\).

Both have y-intercepts of 4 which makes it easy to identify in the graph.

Answer 6

Oh! Thank you! That was stupid easy... can't believe I had to ask.

Answer 7

You are welcome.
