Question 13 • SS26 Math 2 S1 [M2950OX]

The length of time in hours of two airplane flights are represented by the following functions, where x is the number of miles for the flight:Flight A: f(x) = 0.003x – 1.2Flight B: g(x) = 0.0015x + 0.8Which function represents the total of the flight times, h(x) = f(x) + g(x)?

Answer
A
h(x) = 0.0015x – 2
B
h(x) = 0.045x – 0.4
C
h(x) = 0.0045x – 0.4
D
h(x) = 0.0045x – 2

Explanation

Add the two flight-time functions by combining their x-terms and constants: h(x) = (0.003 + 0.0015)x + (−1.2 + 0.8). This gives h(x) = 0.0045x − 0.4, which is choice C.
