• Exponential Function - An exponential function takes on the form of ex, and it can also take on the form of cbx, so it doesn't necessarily need to have the number "e".
• "e" - e is the mathematical constant that equals 2.71828...
• Asymptote - An asymptote of a curve is a line that as the curve approaches it the distance between the curve and the asymptote approaches zero. So the curve is leveling out at a value but will never actually reach that value.
