Opportunity Cost: Tom took a job at a grocery store during his summer break. At the end of
the summer, he managed to save $500 from
the job. Tom would like to purchase a new
television for his bedroom, while his parents
have advised him to open a savings account. A
new savings account earns 2 percent interest
per year. If Tom chooses to purchase the
television instead, what is the marginal cost or
marginal benefit after one year?

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.
