Which statements correctly describe the graph of the function f(x) = x - 2x2 - 19x + 20? Select three options.
As the x-values increase, the y-values always increase.
As x approaches negative infinity, y approaches negative infinity.
The domain of the function is all real numbers.
The range of the function is y > 20.

  q

step-by-step explanation:

each line from a vertex to the midpoint of the opposite side is called a median. the point where the medians intersect, point q, is the centroid.

the centroid of δabc is point q.

y = 3x+4

step-by-step explanation:

to find the slope

slope = (y2-y1)/ (x2-x1)

    = (-8-4)/ (-4-0)

    = -12/-4

  = 3

using the slope intercept form of a line

y= mx+b

we know the slope is 3

we know the y intercept is 4 ( the point where it crosses the y axis or x=0)

y = 3x+4
