26) Halla used her graphing calculator to graph three several polynomial features on the same axes. The equations of the functions appeared to be several, but her calculator showed only two different graphs. She concluded that two of her functions had been equivalent.

a) Is her conclusion correct? Explain.

b) How could she determine which, if any, of the capabilities were comparable without using her graphing calculator?

27) a) Consider the linear features

and

. Suppose that

. Show the fact that functions should be equivalent.
