The graph below represents the amount of change Jaxon would receive, y, if he bought a item with a cost of x. Jaxon’s Change A graph with cost of item on the x-axis and change on the y-axis. The line goes through points (1, 9), (2, 8), and (3, 7). Which equation represents the graph? y = 10 – x y = x – 10 y = –x – 10 y = 10 + x

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.
