In three or four sentences, describe how a person buys and sells stock.

here is my answer

Step-by-step explanation:

A company sells shares of stock, and a person visits a broker and puts in an order to buy stocks. The person watches the stock they want to buy to see if it's gaining or losing money. The person puts in an order for the stock if they want to buy it.

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.
