A rational function g has the lines x=2 and x=-2 as vertical asymptotes, the line y=4 as a horizontal asymptote, and numbers 3 and 1 as zeros. Find a formula for g(x). So I got g(x)=(4x^2-16x+12)/(x^2-4) Is this correct

State the number of positive real zeros, negative real zeros, and imaginary zeros for g(x)= 9x^3 - 7x^2 + 10x - 4. The only thing I know is that there are 3 sign changes.

Find all possible rational roots using the rational root theorem. 3x^3 + 2x^2 - 1 = 0 plus/minus 1/3 and plus/minus 1?

Is it possible to find a rational function that has x-intercepts (-2,0) and (2,0), but has vertical asymptote x=1 and horizontal asymptote of y=0? The horizontal asymptote and the x-intercepts parts stump me. If you can't reach y=0, then how can you get the x-intercepts? And I...
