Natalie is the creator of Better Brain, a new mindfulness app for teens. The app currently has 1,262 downloads, and Natalie has set a goal of doubling the downloads every month. Write an exponential equation in the form y=a(b)x that can model Natalie's goal for the number of downloads, y, in x months. Use whole numbers, decimals, or simplified fractions for the values of a and b. y = ​ (a)   (​ (b)   )​ ^x

Write the equation of the exponential function.

Answer explanation

The y-intercept is (0,2), so a = 2.

Find b by dividing a y-value by the previous y-value.

b = 8/2 = 4
