Question

Determine whether each function is a one-to-one function.If it is one to one, then write the inverse function. PART A:{(7,9),(13,6),(3,9),(11,-4),(1,7)}. PART B:{(11,8),(5,6),(3,7),(21,2),(2,5)}

Answer 1

A:{(7,9),(13,6),(3,9),(11,-4),(1,7)}. inverse={(9,7),(6,13)(9,3),(-4,11),(7,1)}

B:{(11,8),(5,6),(3,7),(21,2),(2,5)} inverse={(8,11),(6,5)(7,3),(2,21),(5,2)}
