8, A parametric equation is given by 3t 1+1 3t2 1 + t3 x= , y= (Note that the denominator approaches 0 when / approaches-1) Plot the func- tion (the plot is called the Folium of Descartes) by plotting two curves in the same plot-one for -30 sis-1.6 and the other for -0.6s1s40. x2-4-7 x-x-6 9. Plot the function f(x) = for-6 6 . Notice that the function has two vertical asymptotes. Plot the function by dividing the domain of x into three parts: one from -6 to near the left asymptote, one between the two asymptotes, and one from near the right asymptote to 6. Set the range of the y 20 to 20
