Front

The value of a car depreciates at a rate of 8% per year. What is the decay factor?

Back

.92

Front

Function with initial amount of $15 and 35% increase each year: y = 15(35)^x, y = 15(1.35)^x, y = 15(0.35)^x, y = 35(1.15)^x

Back

y = 15(1.35)^x

Using the table below, find the equation that matches: y = 20(2)^x, y = 20(1/2)^x, y = 2(20)^x, y = 20(1.25)^x

Back

y = 20(1/2)^x

Front

Equation for the graph of the exponential function: y = 4(2)^x, y = (4)^x, y = (2)^x, y = 2(4)^x

Back
