Question 877608
{{{g(x) = 1 - x}}}



{{{g(-2) = 1 - (-2)}}} Replace x with -2



{{{g(-2) = 1 + 2}}}



{{{g(-2) = 3}}}



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



{{{f(x) = 4 - x^2}}}



{{{f(g(x)) = 4 - (g(x))^2}}} Replace x with g(x)



{{{f(g(-2)) = 4 - (g(-2))^2}}} Replace x with -2



{{{f(g(-2)) = 4 - (3)^2}}} Then plug in {{{g(-2) = 3}}} (we computed this earlier above).



{{{f(g(-2)) = 4 - 9}}}



{{{f(g(-2)) = -5}}}
