Exponential function Practice 2

A small private school with a graduating class of 40 students in the year 2019 predicts that its graduating class will increase by 5% each year.

What function best represents this situation?

• $5,368,709.12 

• $10,737,418.24

•  $1,073,741,824

Is the pictured graph growth, decay, or linear or none?  

• Exponential Growth
• Exponential Decay
• Linear
• None

Pick the equation that is exponential growth

• y=2(0.5)^x
• y = 0.5(2)^x

In an exponential function, what does the 'a' represent? "a" is sometimes referred to as the initial value, but where would it appear on a graph?

• SLOPE
• RATE OF CHANGE
• Y-INTERCEPT
• COMMON RATIO

What is the common ratio for the sequence:
64, 48, 36, 27...

• 4/3

• 3/4

• -16

• -7

What is the common ratio for the sequence:
3, 15, 75...

• 12
• 1/5
• 5
