Observe what happens if the base is not positive: Why do we limit the base to positive values other than 1? This situation is represented by the growth function [latex]P\left(t\right)=1.25{\left(1.012\right)}^{t}\\[/latex], where t is the number of years since 2013. Generalizing further, we can write this function as [latex]B\left(x\right)=100{\left(1.5\right)}^{x}\\[/latex], where 100 is the initial value, 1.5 is called the base, and x is called the exponent. To evaluate an exponential function with a form other than the basic form, it is important to follow the order of operations. 2) State the constant ratio of an exponential function.

In more general terms, we have an exponential function, in which a constant base is raised to a variable exponent. Two squared is 4; 2 cubed is 8, but by the time you get to 2 7, you have, in four small steps from 8, already reached 128, and it only grows faster from there. In this exponential function, 100 represents the initial number of stores, 0.50 represents the growth rate, and [latex]1+0.5=1.5\\[/latex] represents the growth factor. Algebra 1 Curriculum Unit 7 {Buy the full curriculum HERE} This unit includes three single day review lessons that cover the following skills : Company A has 100 stores and expands by opening 50 new stores a year, so its growth can be represented by the function [latex]A\left(x\right)=100+50x\\[/latex].
