For each pair of functions f and g below, compute and simplify the function gof and find Dom(gof) as well. Remember that Dom(gof) cannot be larger than Dom(f)

Problem 1. The functions are f(x) = x²-1 and g(x)=ln(x)

Problem 2. Let a,b,c,d, E R such that ad-bc 0 and c 0 as well. The functions are then

f(x) = (ax+b)/(cx+d)

and

g(x)= (-dx+b)/(cx-a)
