Question

Two students in your class, Tucker and Karly, are disputing a function. Tucker says that for the function, between x = -3 and x = 3, the average rate of change is 0. Karly says that for the function, between x = -3 and x = 3, the graph goes up through a turning point, and then back down. Explain how Tucker and Karly can both be correct, using complete sentences.

Answer 1

Both Tucker and karly can be correct because of the y values when x is equal to -3 and 3. The formula for average rate of change is the change in y divided by the change in x; y(b)-y(a)/x(b)-x(a).

Answer 2

Both Tucker and karly can be correct because of the y values when x is equal to -3 and 3. The formula for average rate of change is the change in y divided by the change in x; y(b)-y(a)/x(b)-x(a).

Answer 3

So how am I supposed to explain this just what you said?
