Identify the exponential functions below and there could be more than one.
00:04
Let's talk about what exponential functions look like.
00:07
Exponential functions, we can have an f of x, g of x, whatever name is going to be a times b to the x.
00:16
Well, when you look at that and initially look at all your choices, you say, well, they look like they're all exponential then.
00:22
They are an exponential form, but are the exponential functions? for this to be an exponential function, there are limitations on the base, because with certain things kind of funny when they have certain kind of numbers.
00:38
So we need to make sure that our base, if your base is zero, it's just going to be a flat line all the time.
00:44
So we've got to make sure our base is not equal to zero...
