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.
Linear, Quadratic, and Exponential Models is a free educational video by Khan Academy.It helps students in grades HS practice the following standards HSF.LE.A.3,HSS.ID.B.6,.
1. HSF.LE.A.3 : Observe using graphs and tables that a quantity increasing exponentially eventually exceeds a quantity increasing linearly, quadratically, or (more generally) as a polynomial function..
2. HSS.ID.B.6 : Represent data on two quantitative variables on a scatter plot, and describe how the variables are related..
