So if we wanted to sketch this polynomial, well, we know we have x intercepts at x is, let's say, x is equal to 1 and x is equal to negative 2.
00:16
And so now let's look at the end behavior.
00:19
Well, if x approaches positive infinity, if x approaches positive infinity, then we have infinity minus 1 times infinity plus 2.
00:29
Well, this gives us a positive infinity.
00:31
So our function approaches positive infinity.
00:36
And so when x approaches negative infinity, we have, again, this negative infinity times a negative infinity.
00:43
So our function or our polynomial also still approaches positive infinity...
