Question 694143: if f(x)= 4x-x^2 and g(x)= 1/x, then (fog)(1/2) is equal to

g(x) = 1/x
g(1/2) = 1/(1/2)
g(1/2) = (1/1)*(2/1)
g(1/2) = 2
-------------------------------------------------------
f(x) = 4x - x^2
f(g(x)) = 4(g(x)) - (g(x))^2
f(g(1/2)) = 4(g(1/2)) - (g(1/2))^2
f(g(1/2)) = 4(2) - (2)^2
f(g(1/2)) = 4(2) - 4
f(g(1/2)) = 8 - 4
f(g(1/2)) = 4
(f o g)(1/2) = 4
