24%

Step-by-step explanation:

25.95 ÷ 100 = 0.2595 this is one percent in money/ 31.95 - 25.95 = 6 now we need to make the percent equal one dollor/ 0.2595 x 24 = 6.228/ this is the closest to six you can get. this means the price was raised 24%.

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.
