So for this question, we're given y is equal to x cubed minus 2x squared plus x minus 1.
00:15
And then we're also given y is equal to negative x squared plus 3x plus minus 1.
00:28
We're asked, okay, do we want to solve it graphically or algebraically? so this one actually looks pretty neat if we solved it algebraically.
00:38
So that's the route i'm going to take.
00:41
And these are pretty long functions.
00:44
So that would be time -consuming, typing into your calculator.
00:48
So let's go ahead and solve it algebraically.
00:51
So you can see that both of these are already solved for y.
00:54
And it's safe to say that y equals y.
00:57
So we can just set these two x parts equal to each other.
01:02
So we'll get x cubed...
