I think to find the y - axis you should sub x=0 
Therefore, y=5(0)+2 
 =2
Hence the answer is (0,2)
I'm sorry if this is wrong!

Answer:
f(x) = x(x-1)
Step-by-step explanation:
The easy way to do this is to look at it graphically. an inverse function is reflected across the line y=x. f(x)=x(x-1) is an upward opening parabola when reflected, there are two y-values for all positive values of x. A function can only have one y for every x.
