Question 1023981
 Use f(x) = 4x − 2 
 g(x) = 5 − x^2 to evaluate the expression.
-----------------------------------------
(a) (f ○ g)(−2) = f[g(-2)] = f[5-(-2)^2] = f[1] = 4-2 = 2
--------------------------
(b) (g ○ f)(−2) = g[f(-2)] = g[4(-2)-2] = g[-10] = 5-(-10)^2 = 5-100 = -95
==========================
