So what is the general formula for an exponential function? well, f of x equals a is, which is my starting value, or if i have no transformations, this is also known as my y intercept times b, my growth rate to the x power.

Okay, so i have the point 024, or excuse me, 0, 4, and then 1 .24.
00:28
So i know that my starting value is going to be approximately 4, right? i'm starting at 4, and then when i go from 0 to 1, what's my growth rate? what do i have to multiply by 4 to get 24 times 6? so that would mean exponential growth.
00:43
If i go to my next value, my next value would have to be multiplied by 6 as well, because i'm multiplying by the same number each time or dividing by the same number.
00:51
So my growth rate is not 24, but i'm growing from 4 to 24 by 6...
