Question 1088427

g={(4,-2),(2,1),(1,3),(0,-2),(-3,-3)} inverse

 finding an inverse is simply the swapping of the x and y coordinates

inverse={(-2,4),(1,2),(3,1),(-2,0),(-3,-3)}


your inverse is {{{NOT}}} a function 

if any x's repeat is {{{NOT}}} a function, and in your case (-2,4) and (-2,0) have same x’s
