Question

Find the exponential function f(x)=C a^x whose graph goes through the points (0,3) and (3,24).

Answer 1

Put x = 0, y = 3
and x = 3, y = 24
You will get 2 equations and 2 unknowns C and a.
And you can solve for both.
To find 'a' you will have to take log on both sides.

Answer 2

thanks i got it
