Exponential Functions Two Points

What are two points on the graph of y = 5(3)^x?

• (0, 3) and (1, 15)

• (0, 5) and (1, 15)

• (0, 3) and (1, 5)

• (0, 5) and (1, 3)

Which of the functions shows an initial amount of $15 and an increase of 35% each year?

• y = 15(1.35)^x

There is a culture of bacteria that begins with 5000 cells and dies by 30% each year. Write an exponential model to represent the situation.

• y = 5000(0.70)^x

• y = 30(5000)^x

• y = 5000(1.30)^x

• y = 5000x^x
