Daniel’s Print Shop purchased a new printer for $35,000. Each year it depreciates at a rate of 5%. Would the equation for the value of the printer show Exponential Growth or Decay?

• DECAY

• GROWTH

Which equation is representative of the graph?

• Exponential growth

• Exponential decay

Which equation is representative of the graph?

• Exponential growth

• Exponential decay

Choose the equation that shows exponential decay.

Pick the equation that is exponential growth

• y=2(0.5)^x
• y = 0.5(2)^x

The value of a car is $15,000 and depreciates at a rate of 8% per year. What is the exponential equation?

• y=8(15,000)^x

• y=15,000(1 + .08)^x

  or y=15,000(1.08)^x

• y=15,000(0.92)^x

  or y=15,000(1 - .08)^x

• y=15,000(0.08)^x

A new savings account is opened with $400 and gains 3% every year. What is the exponential function?

• f(x)=400(1+3)^x
• f(x)=400(1-0.03)^x
• f(x)=400(1+0.03)^x
• f(x)=400(0.03)^x

If the rate of increase is 5%, what do you plug in for r in the exponential growth?

• 5

• 0.5

• 0.05

• 0.005
