(2,20) means that the 2 is 2 hours and 20 is 20\$. so there both 20\$ for 2 hours only the same price. like it says. so, the dunk tank and the bounce house are the same price (20\$) for the same amount of time (2 hours).

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.

Cancel the 2 to get x then x-1 divided by x
