Linear, Quadratic, and Exponential Models
By Khan Academy
Watch this video to learn how to identify linear and exponential functions from input output tables. Linear functions grow by equal differences over equal intervals, so as x increases or decreases at a constant interval, you add or subtract a constant for each corresponding y interval. Exponential functions grow by equal factors over equal intervals, so as x increases or decreases at a constant interval, you multiply or divide a constant for each corresponding y interval.
Understanding logarithms as inverse exponentials
By Khan Academy
Sal rewrites 100=10^2 as a logarithmic equation and log_5(1/125)=-3 as an exponential equation.

Identifying Exponential Models
By Khan Academy
Watch this video to learn how to identify exponential models. An exponential function has the form y = Arx and models when a constant change in x results in a proportional rate of change in y. In other words, exponential functions grow by equal factors over equal intervals.
