What must be true about the average rate of change between any two points on the graph of an increasing function?

Answer with explanation:

Average Rate of Change between any two points

                  =Difference of y coordinates divided by Difference of x coordinates

⇒   If two points have coordinates , (x,y) and (a, b),then Slope is given by the formula

⇒For an increasing function , if

       b> y

then, a > x.

⇒⇒For, increase in value of x, value of y also increases for an increasing function or for any two points on the graph of an increasing function.

step-by-step explanation:

draw the shape and you will see that f and k are actually at adjacent vertices (points of the hexagon that are neighboring).   so find the distance between (1,2) and (4,2).   that is easy since (1,2) and (4,2) is just a vertical distance to count, which is 3.   it is a regular polygon which means all sides are congruent.   you have 6 sides (hexa) so multiply 6 by 3 to receive 18.
