Write a rational function with no vertical asymptotes and no holes. explain.

Sure! One example of a rational function with no vertical asymptotes and no holes is the function:

f(x) = (x^2 + 1) / (x^2 + 1)

This function simplifies to f(x) = 1 for all x, since the numerator and denominator are always equal. Since the function is always defined and equal to 1, there are no vertical asymptotes and no holes in the graph of this function.
