Given the following functions f(x) and g(x), evaluate (g∘f)(−3). Enter answers using exact values. f(x)=2x^2+3x+2 , g(x)=-1/5x-2

Question

Please reply with answer

Answer 1

(g•f)(-3) = g(f(-3)); f(-3) = 2(-3)² + 3(-2) + 2 = 18 - 6 + 2 = 14; g(14) = -1/5(14) - 2 = -14/5 - 2 = - 24/5;

(g•f)(-3) = - 24/5
