... Holes: If (x – b) is a factor of the numerator and denominator of a rational function, then there is a hole in the graph at x = b, unless there is a vertical asymptote at x = b. To find the y-value, substitute the x-value into the simplified version of the function. Standard form of the Equation of ...
