True or False Word problem

Question

If f is a one-to one function and the graph of f lies completely within the third quadrant, then the graph of f ^-1 lies completely within the third quadrant. True or False?

Answer 1

Hi Sarah,

 

Since f is a one-to-one function, (x,y) is on the graph of f if and only if (y,x) is on the graph of f^-¹.  See if you can take it from there.
