A parking garage allows users to park the first hour free and then charges $2.50 for each additional hour or fraction of an hour. Which equation represents this situation?

An equation that could be used to represent this equation is:

y = 2.5x - 2.5

Step-by-step explanation:

x = number of hours

y = the amount that the user has to pay

You have to multiply the number of hours by $2.50. Then subtract $2.50 from that amount for the first hour that is the parking garage allows the user to park for free.

f(x)=2.50[x-1]

Step-by-step explanation:

if the eqn of the parabola is f(x) = (x-4)(x+2), we need to mult. this out to find the coordinates of the vertex.

then f(x) = x^2 + 2x - 4x - 8, and f(x) = x^2 - 2x - 8.

one way in which you can find the vertex is to calculate x = -b / (2a).   here, that comes to

        )

x = = 1.   f(1) = 1^2 - 2(1) - 8 = - 9.   vertex is at (1, -9).

        2(1) 

find another point on the curve:   let x=0, for which y=-8.   then (0, -8) is on the curve.   plot the vertex and this point and draw a smooth parabola thru both.

hope this
