The functions of f and g are defined as follows

Question

F (x) = 2x³ + 6 G (x) = -4x + 2

Find f(-3) and g(4)

F( -3) =

G(4) =

Simplify the answer as much as possible thank you

Answer 1

Hello David

f(x) = -4x + 2; f(-3) = -4*-3 +2 = 14

2x³ + 6 G (x) = -4x + 2; 2*4^3 +6*g(4) = -4*4 +2

128 + 6*g(4) = -14. (cancel 128)

6*g(4) = -142. (cancel 6)

g(4) = -23.67

hope that helps
