F.LE.A.1a, b, c and F.LE.A.3 - Modeling with Linear and Exponential Functions

Two revenue models (in thousands of dollars) for a subscription product are proposed:

A device’s battery charge is checked each hour. Two models describe different charging/usage behaviors (t in hours):

Use the table below to determine the value of y when x = 4.

A school club tracks followers on its official page each week. Where x is the number of weeks after the start of the school year and y is the total number of followers.

A bank offers a sign-up special for savings accounts, compounded annually:

For each situation, choose the function (D, L, or E) that best models it. Assume equal increments of time.

The graph shows two functions, f and g.

Each table shows a function with equal increments in x.

Two students are modeling the same data set. The table shows how a quantity y changes with x:

Ana is analyzing the two functions shown below.
