All right, i've already taken the liberty of writing the function for question number 25.
00:09
And notice that it says 3x to the fourth power and a bunch of stuff that doesn't matter when you're just thinking about end behavior.
00:19
So i wrote blah, blah, blah, because the rest of the function just doesn't matter when we consider the end behavior.
00:27
Now, i notice that the leading coefficient is 3, which is a positive number.
00:43
And i notice that the degree or the leading exponent, i'm going to rate degree, is not only 4, but it's even.
01:00
All right, positive and even means up and up.
01:08
I'm going to draw a little x, y -axis.
01:10
It means if it's positive, then what happens on the right side of the y -axis is up.
01:29
And if it's even, then the left side is the same as the right side.
01:37
And so it's up and up...
