justification of reasoning for your choice.a.The domain of the function is,11,.b.The factor (x+ 1) is a non-canceling factor in the numerator ofthe equation ofG(x).c.The degree of the numerator is less than the degree ofthe denominator.
Multiple Choice & Free Response Items for the Pre-AP* Mathematics ClassroomPage 216Mark Sparks © 2014Free Response #7 Grading RubricFree Response Part A3 points total____1False____1The domain of a rational function is,except for the restricted values of the function.____1From the graph,x=2 is also a restricted value ofG(x) because there is a hole in the graph whichmeans that the domain should be,11,22,.Free Response Part B3 points total____1True____1A non-canceling factor in the numerator of a rational function indicates anxintercept on thegraph of the function.____1The graph ofG(x) has anxintercept atx=1 so the factor (x+ 1) should be a non-cancelingfactor in the numerator.Free Response Part C3 points total____1False____1When the degree of the numerator is less than the degree of the denominator, then the graph ofthe rational function has a horizontal asymptote aty= 0.____1The graph ofG(x) has a horizontal asymptote aty= 1, not aty= 0.Thus, the degree of thenumerator cannot be less than the denominator.
