Analyze Exponential Functions

A(n) ________________ function will MULTIPLY the same number each time.

• Linear

• Quadratic

• Exponential

• All of the above

The table below represents the function F. The equation that represents this function is

• F(x) = 3^x

• F(x) = 3x

• F(x) = 2^x + 1

• F(x) = 2x + 3

If a population of cells triples every hour, which function represents p(t), the population after t hours?

• p(t) = 3(100)^t

• p(t) = 100(3)^t

• p(t) = 3t +100

• p(t) = 100t + 3
