The gas mileage of a car (in miles per gallon) is highest when the car is going about 45 miles per hour and is lower when the car is going faster or slower than 45 mph. Graph gas mileage as a function of speed of the car.

Determine whether the statement makes sense or does not make sense, and explain your reasoning : "My body temperature is a function of the time of day."

A user is charged P500.00 monthly for a particular mobile plan, which includes P150.00 free text messages. Messages in excess of 150 are charged P1.00 each. Represent the amount a consumer pays each month as a function of the number of messages m sent in a month.

The cost of fuel is the largest component of cost of ownership for most vehicles. Fuel cost is​ (almost) inversely proportional to gas​ mileage; higher gas mileage means lower fuel cost and​ vice-versa. If you keep track of the number of miles driven on each tank of gas as well as how much gas is​ purchased, it is easy to calculate gas​ mileage; many cell phone apps exist to track this. The data in the following table is the gas mileage for Mr.​ Hebert's 2015 Jeep Wrangler Unlimited.     12.85 14.98 15.36 17.09 18.86 13.28 15.11 15.62 17.50 19.07 13.48 15.12 15.65 17.66 20.91 14.65 15.13 16.41 18.17 21.17 14.71 15.14 16.80 18.27 22.11 f.

The height (in centimeters) of a candle is a linear function of the amount of time (in hours) it has been burning. When graphed, the function gives a line with a slope of -0.6. See the figure below. Suppose that the height of the candle after 14 hours is 15.6 centimeters. What will be the height of the candle after 20 hours? Candle height (in cm) 15.6 14 Burning time (in hours) centimeters X S
