Question 75386: Pleas help with the problem below. I really appreciate your help.
A trolley company has an average of 800 riders per day, at a fare of $2.25 per ride. They conducted a survey and found that they will lose approximately 40 customers per day for each $.25 increase in fare.
a) Let the number of riders be a function of the fare charged. Graph the function and find the slope of the graph.
b) If the trolley company was to eliminate the fare, ($0 or free fare), how many riders will they have each day?
c) If the trolley company raises the fare too high, no one will be willing to ride. Starting at what price (of the fare) will no one be willing to ride?

I duplicated the graph with points (-19, 20)and (20, -19)I am not sure this is correct but the line is showing exactly what the graph is in the book.
The equations are
a)y=-x^2+1
b)y=2x
c)y=x^2-4x
d)y=-x=1
e)y=-x^2+3x
f)y=x^2+1
g)y=x+1
h)y=2x^2
Thanks for your help.

Question 75693: Match each graph with the correct equation on the right.
This graph is a curve graph that starts at points(-1,20) the curve drops down to points (3, -4) and back up to points (6,20). I am not sure if these are right I just duplicated the graph to get the coordanance. The equations are:
a)y=-x^2+1
b)y=2x
c)y=x^2-4x
d)y=-x=1
e)y=-x^2+3x
f)y=x^2+1
g)y=x+1
h)y=2x^2
Thanks for your help.
