I am VERY confused to even know how to begin to solve this problem. I need someone to walk me through this problem. Medal as always. Two students in your class, Wilson and Alexis, are disputing a function. Wilson says that for the function, between x = -1 and x = 1, the average rate of change is 0. Alexis says that for the function, between x = -1 and x = 1, the graph goes up through a turning point, and then back down. Explain how Wilson and Alexis can both be correct, using complete sentences.

    Well I'm not sure, it just says explain how both of them ~could~ be correct. For this should I use my knowledge of graphing functions and translation meanings or something different?

    well if slope is zero you will draw horizontal line

    do you have graph with this question or table ?

    No there is no graph or table.

    i will use slope formula (average rate of change - slope )\[\huge\rm \frac{ y_2 - y_1}{ x_2 -x_1 }\] if slope is 0 then you should get 0 at the numerator substitute x's values x=1 and x=-1

    Alexis says that for the function, between x = -1 and x = 1, the graph goes up through a turning point, and then back down. goes up through a turning point, then back down? ?

    well how would you get 0 at the numerator in order to get zero both y values should be the same like y_1 = 2 y_2 = 2 then you will get 0 \[\frac{ 2-2 }{ 1-(-1) } = \frac{ 0 }{ 2}\] when slope is zero you will draw horizontal line |dw:1441304852375:dw| x values are increasing but y's is constant

    so i guess he meant x values are going up y values are the same
