f(x) = (3x) / (x2 + 1). Show that f-1(x) = (6 - 3x2) / (x2 + 2)2

f(x) = (3x) / (x2 + 1). Show that f-1(x) = (6 - 3x2) / (x2 + 2)2

f(x) = (2x-2)/ x2+x-2 g(x) = a/ b+x

Need this to graph please have no idea , need all intercepts, asymptotes and domain

Find a rational function that represents a graph that has a vertical asymptote at x=2 and x= -3 and a horizontal azymptote at y=0. the answer is f(x)= (x-4)/(x2+x-6) I...

given f(x)= t3-2t2-8t/t2-4 find the domain, asymptotes, holes and intercepts. I know that to find the x intercept you set y=0 and solve for x but I am unsure how to isolate x...
