Olivia earns $12 an hour at the grocery store. she kept track of her hours per week and how much she earned in the following table. graph the values in the table on the coordinates plane shown. what will you label the x-axis? what will you label the y-axis? at what intervals will you label the x-axis? at what intervals will you label the y-axis? label the grid and graph the points. from the table, what points will you graph?

there's no attachment, but i'm betting the axes will be olivia's hours and earnings. the x-axis will be her earnings, and the y-axis will be her 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.

hope this
