Car A and Car B were in a race. The driver of Car B claimed that his car was twice as fast as Car A. Car Speeds A bar graph titled Car Speeds has Car on the x-axis, and speed (miles per hour) on the y-axis, from 170 to 172. Car A, 171; Car B, 172. Do you agree with this claim? Why or why not? a. Yes, because the bar for Car B is twice as tall as the bar for Car A. b. Yes, because the speed of Car B is twice that of Car A. c. No, because Car B was only 10 mi/hr faster than Car A. d. No, because the vertical scale exaggerates the differences in speed.

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.
