I have been asked to draw the graph of the function f(x)= (x+3)/(x-2)
I have found where it cuts the y-axis by putting x=0 but am unsure of how to find the x value.
I found the inverse of f(x)= (x+3)/(x-2) which gave me x= (y+3)/(y-2) then set y=0 which again gave me x=-3
I have checked on graphing calculators and this is the correct answer but i think my method is wrong!
Could anyone please help?
