Quiz : Graphing Exponential Functions
Instructions: Please complete this quiz by choosing the correct answer for each question. You can take this quiz as many times needed.
Question #1
The numbers suggested to be use to substitute for x were 1, 2, 3, 4, and 5.
Question #2

Did the graph in the video show exponential growth or exponential decay?

Question #3

What was the y-intercept of the graph in the video? 

Question #4

Finish this statement about the graph in the video. As x approaches -infinity, y approaches...

Question #5

What are the correct coordinates for y=3^x if using -2, -1, 0, 1, and 2 as the independent variable?

Question #6
The point (-2,-4) would be a correct point on the graph y=2^x.
Question #7

Which point is NO located on the graph of the equation y=5^x?

Question #8
In the video, it was said that with that specific example, y=5^x, the graph will get closer and closer to the x-axis but never touch it. Explain why this is true. 
Question #9
Can you come up with an Exponential Function that would cross/touch the x-axis? Explain
Question #10
If you had to pick one part of graphing exponential functions that was hardest for you to understand, what would it be?
