What are exponential graphs?

Exponential graphs have equations of the form y = a^x where a is some (usually rational) number

When a > 1 these graphs increase rapidly in the y direction and never cross the x axis

Exponential graphs are of the form y = a to the power of x, where a is a number. The y-intercept is 1 (when x = 0, the power is 0 and any number to the power of 0 is 1).

Here is an image of the graph y = 2 to the power of x.
