use the asymptotes and intercepts to make a quick sketch of the function f(x)= x-2 (numerator) x+4(denominator) and its reciprocal f^r = x+4 (numerator) x-2 (denominator) on the same set of axes.

b) describe the symmetry in the graphs in part a)

c) determine the intervals of increase and decrease for both f and f^r, how do the sets of intervals compare?

d) would the pattern occur for all pairs of functions f(x)= x+b (numerator) x+d and f^r(x) = x+d (numerator)and x+b (denominator)? explain why or why not?

REINY OR WHOEVER IS READING THIS, I JUST NEED TO KNOW THE ANSWER FOR D
