Question

What does it mean if the rate of an airplane is modeled by the function f(x) = 1x + 500?

A) The airplane's rate increases exponentially.
B) The airplane's rate increases linearly.
C) The airplane's rate is constant.
D) The airplane's rate decreases.

Answer 1

Answer 2

Answer: The air plane rate is constant
