For each scatter plot, decide what type of function you might choose as a model for the data. (a) (b) P 0 O linear function, of the form f(x) function, of the form f(x) = ax³ + bx² + cx + d exponential function, of the form f(x) = a · bx + c = mx + b a O reciprocal function, of the form f(x) = X O root function, of the form f(x) = a y 0 bx + c = mx + b O linear function, of the form f(x) cubic function, of the form f(x) = ax³ + bx² + cx + d

A car with 4,000 miles is purchased. The car averages 20 miles per gallon. The linear function m(x)=20x + 4,000 models the total mileage on the car, m(x), in miles, for a given number of gallons of gas, x. What is the range of the function?
