Key Features of Exponential Functions

What does the b-value of an exponential function indicate about its graph?

• The y-intercept.

• If the graph is increasing or decreasing.

Which of the following is an increasing exponential function whose y-intercept is 50?

• y = 50(.05)^x

• y = 50x - 4

• y = (2)^x + 50

• y = 50(1.4)^x

Which of the following statements are true of the exponential function? Select all that apply.

• The graph has been shifted up 3 units from the parent function.

• The function represents exponential growth.

Which of the following statements are true about the function below? Select all that apply.
f\left(x\right)=0.5\left(2\right)^x-1

• The function represents exponential growth

Which equation models the graph?

Which function models the values in the table?

The population of deer in a certain town was 10,000 in 2015. Each year the population has decreased by 10%. That is, each year the population is 90% of what it was the previous year. Which equation models the population of deer since 2015?
