Hello! I have a crazy instructor and gave me this problems.

A) Consider f(x)= mx+k, , and h(x) = ax^2+bx+c.

1.) True or False?

2.) Show true or false? The points of intersection between g(x) and are on the line y=x.

3.) Show is the graph of the inverse relation for h(x).

Honestly I don't have Idea how am I going to solve this problem. please help! Thank you!
