Let the number of mile travelled be x. And total cost of the ride be y.
The given problem can be represented as a linear function.
y = mx +c, where m = 0.75 and c = 2.5
y = 0.75(x) + 2.5 , required function
Given, x = 17 miles
So, y = 0.75(17) +2.5
Domain of the function: Positive Integer or [0,inf)
Range: [2.5, inf)
Function is continuous.
ordered pair (x,y): (17,15.25)
