Functions

Exponential functions can either be growth or decay
Growth would mean it goes up positively and decay would mean it goes down negatively

Exponential functions have a few defining features
- Asymptote
-

Sine functions always go throught the 0,0 intercept

You can tell a function is a polynomial by ...
- The domain is any real number
- A smooth and unbroken curve

Cosine functions can never touch the 0,0 intercepts, like the sine functions do.

Linear functions are straight lines that have no curve, only a slope, Y intercept and X intercept.

Sine function= y = sin X

Cosine function= y = cos x
