X-intercept? y=0
Y-intercept? x=0
Vertical Asymptote? the limit as X approaches X sub zero of the function = + or - infinity
Horizontal Asymptote? the limit as X approaches + or - infinity of the function = L, graph levels off at y=L at ends.
Oblique Asymptote? is degree of numerator exceeds the degree of the denominator by one. divide numerator by the denominator.
Cusp? If: 1) f(x) is continuous at Xsubzero 2) f(x) has a vertical tangent at x=xsubzero 3) fprime(x)goes to infinity on one side and -infinity on the other.
Newton's Method Xn+1 = Xn - (f(Xn)/fprime(Xn))
