You are 330 from home and you are driving home and you are driving toward home at an average of 55mph. Wr Try and equation to represent the situation and find the domain and range of the function

Wouldn't that be 330 miles? Units are important.

Let d represent your distance from home. At the beginning you're 330 miles away, driving home at 55 mph (average). If x represents the number of hours you've driven, then

d (x) = 330 miles - (55 mph) x
