The function f(x) represents the time it takes an airplane to travel east. the function g(x) represents the time it takes an airplane to travel west. given f(x) = 4x + 13 and g(x) = 10x − 2, solve for (f + g)(x) to determine the total roundtrip time.
a.(f + g)(x) = 14x + 15
b. (f + g)(x) = 14x + 11
c .(f + g)(x) = 6x + 11
d. (f + g)(x) = 6x + 15
