How do you graph #f(x)=(x+2)/(x^2+4)# using holes, vertical and horizontal asymptotes, x and y intercepts?
The horizontal asymptote is y= 0 because the denominator exponent is larger than the numerator.
There is an x intercept of -2 because the numerator is
there are no vertical asymptotes because the denominator does not factor.
There are no holes, because no two terms cancel eachother out.
The Y intercept is
