Write an exponential function in the form y=ab^xy=ab x that goes through points (0, 15) and (3,3240).

Respuesta :

The exponential function that goes through points (0, 15) and (3,3240) is:

[tex]y = 15(6)^x[/tex]

What is an exponential function?

An exponential function is modeled by:

[tex]y = ab^x[/tex]

In which:

  • a is the initial value, that is, the value of y when x = 0.
  • b is the rate of change.

The function goes through point (0,15), hence a = 15. When x = 3, y = 3240, hence we use it to find b, as follows:

15b³ = 3240

b³ = 3240/15

b³ = 216

[tex]b = \sqrt[3]{216}[/tex]

b = 6.

Hence the function is:

[tex]y = 15(6)^x[/tex]
