The Lakers played the Bulls. The Lakers scored 70 points in the game. In the first quarter the bulls scored 12 points. In the second quarter the Bulls scored twice as many as they did in the first quarter. In the third quarter they scored 1/3 as many points as they did in the second quarter. How many points did they need to score in the fourth quarter to win the game?

38 points

Step-by-step explanation:

12*2=24*1/3=8+24=32

70-32=38

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.
