The function is [tex]f(x)=12^x[/tex].
This means that as we get from 1 to 2, we have the following values:
[tex]f(1)=12^1=12[/tex], and [tex]f(2)=12^2=12\cdot12[/tex].
Similarly, if we check x=3, we have [tex]f(3)=12^3=12\cdot12\cdot12[/tex].
We can see that as x changes by 1 (with greater values), y increases by a factor of 12.
Answer: multiply by 12
