Answer:

$solve \: when \: (f + g) \:(4) \\ \\ first \: solve \: for \: f(x) \\ \: \\ solution \: .... \\ \\ f(x) = 4x - 3 \\ f(4) = 4(4) - 3 \\ f(4) = 16 - 3 \\ f(4) = 13 \\ \\ \\ now \: solve \: for \: g(x) \\ \: \\ solution \: .... \\ \\ g(x) = {x}^{3} + 2x \\ g(x) = {(4)}^{3} + 2(4) \\ g(x) = 64 + 8 \\ g(x) = 72 \\ \\ (f) - (g) = 13 - 72 \\ (f) -(g) = -59$
