If xy=0
assume that at least x or y=0
3(x-3)=0
therefor
3=0 or x-3=0
3=0 is false
therefor
x-3 mus equal zero
x-3=0
add 3 to both sides
x=3
If you were to replace the x's with 2, your equation would turn into:
(2)^2-4(2)+5
From there, you'd just solve.
4-8+5=1
Your answer would be 1.

To be able to graph this you need to start on -2 on the y-axis then move up 5 then 1 to the right
The dot should be on (1,3)
