I don't know exactly what the parabola looks like, but i do know a function that has, that is written as y equals 2 minus x, that the y intercept is going to be 2, and then the slope is down 1 over 1.

So this graph looks something like this.
00:21
Now the other graph that we have, which is y equals 2x minus x squared, i could easily factor out in x.
00:36
2 minus x.
00:37
So i know the x intercepts are going to be at 0 and 2, but i'm not quite sure where the intersection points will be for sure.
00:45
I do know x equals 2 for sure, but what you can do is set these expressions or equations equal to each other and then solve.
00:55
So how would i solve? i would probably set the left side equal to zero, so i add x squared to the right side.
01:01
If i subtract 2x to the right side, i get negative 2x...
