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

the answer is the option b

the range is all real numbers

step-by-step explanation:

we know that

the absolute value parent function is equal to

see the attached figure to better understand the problem

so

a. it is v-shaped > is true

b. the range is all real numbers > is not true

because the range is the > [0,∞)

all real numbers greater than or equal to zero

c. it goes through the origin > is true

d. the domain is all real numbers > is true

step-by-step explanation:

first one is a: renaming a fraction. second one is c: de-c
