Question 197696
a)


{{{f(x) = 7*abs(x + 4)}}} Start with the given function.



{{{f(x+1) = 7*abs(x+1 + 4)}}} Replace every "x" with "x+1"



{{{f(x+1) = 7*abs(x+5)}}} Combine like terms.



--------------------------------------------



b)


{{{f(x) = 7*abs(x + 4)}}} Start with the given function.



{{{f(x^2+2) = 7*abs(x^2+2 + 4)}}} Replace every "x" with {{{x^2+2}}}



{{{f(x^2+2) = 7*abs(x^2+6)}}} Combine like terms.
