Sophie invested $5000 into an account that will increase in value by 2.3% each year.
Write a function to model this situation.
Which function(s) represents exponential decay.
May be more than one.
Jack bought a new car in 2014 for $28,000. If the value of the car decreases by 14% each year, write an exponential equation model for the value of the car in 2018.
A baseball card that was valued at $200 in 1980 has increased in value by 7% each year. Write a function to model what the value of the card would be in 2017.
Which exponential function represents the graph below?

Which exponential function matches the data shown?

What is the range of the function below?

Don't pick this one. The Range is always the y values. Not the x values.
Don't pick this one. The bottom of the graph is at 4.5. The -2 would apply to the domain.
What is the domain of the function below?

Find the equation that that best fits this data.
