9. A car's speedometer is not always completely accurate. The error in this measurement is based on the number of miles per hour the car is traveling above or below 60mph. The error is measured by the function E (a) = la - 60], where a represents the actual speed of the car. Determine an appropriate domain and range for this function and graph on the set of axes below. Hint: what is the rertex? Wbat is the masimum speed of a car? What is the minimum speed?

Limits

When it comes to calculus, limits are considered to be a very important topic of discussion. The main importance of limit lies in expressing the value of a function as it gets closer to a certain value. Also, limits can help you to understand other topics, such as continuity and differentiability better. In a broader sense, every calculus notion is a limit. Other branches of calculus have also been derived from limits.
