Question

Which rule can be used to describe the growth of the y vales of the function y=12^x over each interval from x=-1 to x=3?

Answer 1

The function is $f(x)=12^x$. 

This means that as we get from 1 to 2, we have the following values:

$f(1)=12^1=12$, and $f(2)=12^2=12\cdot12$.

Similarly, if we check x=3, we have $f(3)=12^3=12\cdot12\cdot12$.


We can see that as x changes by 1 (with greater values), y increases by a factor of 12.


Answer: multiply by 12
