Describe a function g(x)\displaystyle {g{{\left({x}\right)}}} in terms of f(x)\displaystyle {f{{\left({x}\right)}}} if the graph of g\displaystyle {g} is obtained by reflecting the graph of f\displaystyle {f} about the x\displaystyle {x}-axis and if it is horizontally stretched by a factor of 2 when compared to the graph of f\displaystyle {f}.
g(x)=Af(Bx)+C\displaystyle {g{{\left({x}\right)}}}={A}{f{{\left({B}{x}\right)}}}+{C} where
A=\displaystyle {A}=  
B=\displaystyle {B}=  
C=\displaystyle {C}=
