QUESTION 5 The graph of a polynomial function has vertical and/or horizontal asymptotes. o True o False QUESTION 6 Let f(x) = 2x2 x 2 - 1 - is a rational function. Then y=2 is a horizontal asymptote since lim 2x2 x -+ 00 x- - 1 = lim 2 1 =2. The zeros of the denominator of function give that x=-1 and x=1 are vertical asymptotes of the graph of function. o True o False QUESTION 7 Let f(x) =3x#+ 4x'+ 1 is a polynomial function of fourth degree. To find the absolute extrema of a function on a closed interval [-2,1], first, we find the first derivative f (x) = 12x5+ 12x
