Best ResponseYou've already chosen the best response.3when you are dealing with any function \(f(x)=x^w\), a vertical shift is: \(f(x)=x^w+c\) (shift up), OR \(f(x)+x^wc\) (shift down).

Best ResponseYou've already chosen the best response.3I mean \(fx)=x^wc\) for the last equation ...

Best ResponseYou've already chosen the best response.3Say you have a function \(f(x)=x^w\)  \(f(x\cdot k)=(x\cdot k)^w\) that is just increasing the base, and gives you a different function. \(f(x)+c=x^w+c\) ~ shift up when c>0 ~ shift down when c<0. \(kf(x)=k(x)^w\) ~ you are stretching the function when k>1, ~ shrinking when 0<k<1, ~ reflecting the function across x axis and then shrinking it when 1<k<0, ~ reflecting the function across x axis and stretching it when k<1. \(f(x+k)=(x+k)^w\) ~ shift right when k<0 ~ shift left when k>0
