1. Graph the following pairs of functions. What is the domain of each? Where are the vertical asymptotes? Where are the removable singularities? What is the difference between each pair?

(a) f(x) = x + 2 and g(x) = x^2 4/ x2

(b) f(x)= 1/ x+ 2. and g(x)=x2/ x^24

(c) f(x)= 1/ x^2 4 and g(x)= x/x^3 4x
