Solve It! f and g are exponential functions with the same base.

Is the graph of g
● a compression,
● a reflection, or
● a translation

Problem 3 Got It? Reasoning: In Problem 3, would the model of the exponential data be useful if you did not translate the data by 68 units? Explain.
Yes; since a hot drink in this scenario may cool well below room temperature, it is not necessary to translate the data.
No; a hot drink in this scenario will not cool below room temperature. In order to use exponential data, it is important to translate the data left 68 units.
No; a hot drink in this scenario will not cool below room temperature. In order to use exponential data, it is important to translate the data up 68 units. 7

Problem 4 Got It? How can you use a graphing calculator to calculate e8?
Use the ex key, x = 8
Graph y = ex and find y for x = 8
Use the table of values for y = ex and find y for x = 8
All of the above
