For the first one, think about what happens to y when X is zero and as it X tends to infinity. Also, check what values of X give the denominator equal to zero as y will tend to infinity at these values (asymtotic lines)

Check x and y intercepts by setting y to zero and x to zero respectively. Differentiate y with respect to x to find stationary points (i.e. where dy/dx = 0). Differentiate again to find out whether each stationary point is a maximum, minimum, or saddle point. Then use timeforchange's tips and you'll be sorted.
