Question 1144613
.
If f(x)=x^2, find {{{highlight(cross(two))}}} <U>the</U> {{{highlight(cross(functions))}}} <U>function</U> g for which (f o g)(x)=4x^2-12x+9
~~~~~~~~~~~~~~~~~




g(x) = 2x-3.



It is one possibility.
There are other possibilities, too.



First other possibility is  g(x) = -(2x-3).



Second other possibility is  g(x) = |2x-3|.
