Basic Exponential Functions

Don't you just love it when you get a new type of function instead of choclate on valentines day? lol

A basic exponential function is an asymptotic (it never touches any axis) function where the constant "c" is brought to the power of x. EX) Y=2^x. With this function it is also important to remember: when X is negative you will get a fraction for your Y, Also there is no value of x that will give 0. Another thing to remember is when "c" is a fraction and your x is negative you will get a whole number as the negative flips the fraction.

Qualities of this type of function:
When c gets bigger, the function increases quicker.
Domain is always R
It can increase or decrease
Y intercept is always 1
And there is no zero

Well I believe that pretty much sums up the basic exponential function. Feel free to add anything I may have forgotten!
