Determine the linear function fx on the graph 5 A certain co

Determine the linear function f(x) on the graph. 5) A certain county charges a flat fine for speeding, in addition to a fee for each mile per hour a driver goes over the speed limit. A driver who was going 63 mph in a 55 mph zore was fined $159. while another driver who was traveling 58 mph in a 40 mph zore was fined $249. a) Find a linear function f(x) = mx + b whose input is the number of miles per hour over the speed limit that a person was driving and whose output is the fine that must he paid. b) Use the function from part a to determine the fine

Solution

Part a) the graph is linearly increasing function

Part b) the graph is linearly decreasing function

Part c) the graph is a constant function
