Question

a hot - air balloon is flying at an altitude of 150 feet (ft). when the pilot heats the air in the balloon it rises at a constant rate. the altitude of the balloon is a function of the number of minutes it rises. describe the input and output of the function. input (x - value):? output (y - value) 4 min 1750 ft 3 min 1350 ft 2 min 950 ft 1 min 550 ft 0 min 150 ft

Explanation:

Step1: Analyze Input

The function's input is the independent variable. Here, the altitude depends on time (minutes). So input is "number of minutes".

Step2: Analyze Output

The output is the dependent variable, which is the altitude (depends on minutes). So output is "altitude of the balloon".

Answer:

input (x - value): number of minutes
output (y - value): altitude of the balloon
