Question

Problem is down below , there is 3 parts to the problem

Answer 1

First, let's see how the graph of

`y=4^x`

look. We know that it will look something like

The point x = 1 is very important, the result must be 4 when x = 1. Now let's find the graph of

`y=-4^x`

by looking at the graph of

`y=4^x`

The negative means that we have a reflection over the x-axis, therefore, the graph will be like

Using a graphing calculator we can confirm the graph:

The correct answer is the last graph.
