The speedometer on a car shows that the car is going 60 miles per . The function e(x) defined by e(x) = |x - 60| hour represents the error in the speed that the speedometer shows, where x is the actual speed of the car in miles per hour. For example , if your actual speed is 70 miles per hour , the error in the speedomiter display is e(70)=|70-60|=|10|=10| miles per hour. Graph the function.
