Question

Help please, I don’t understand how to do this -

A car can travel 32 miles for each gallon of gasoline. The function d(x) = 32x represents the distance d(x), in miles, that the car can travel with x gallons of gasoline. The car’s fuel tank holds 17 gal. Find a reasonable domain and range for the function. Then graph the function.

Answer 1

The car fuel tank represents the variable x value while the d(x) represents distance it can travel. If the car has 10 gallons of fuel inside its tank, to find the distance that the car can travel would be:



d(x)=32x
d(10)=32(10)
d(10)=320 miles
