Exponential Functions/Equations

What defines an exponential function?

• A function with a constant exponent

• A function where the exponent is a variable

• A function that cannot have negative values

• A function that only includes integers

What does the 'a' value in an exponential function represent?

• The x-intercept

• The slope of the graph

• The y-intercept

• The rate of growth or decay

A wildlife preservation group records the number of squirrels in a city park. The first count recorded is 30 squirrels. A second count of 60 squirrels is recorded six months later, and 120 squirrels are counted at the end of one year. Assuming that no squirrel dies and the growth rate remains the same, which function represents the number of squirrels after x years? (DOK 2)
