Hello, so today we're talking about quadratic equations and when graphing quadratic equation, you're going to have two different types.
00:13
You'll either have it open upwards like that or it will open downwards like that.
00:22
Either way, like if it opens downwards, it's going to have a maximum, if it opens upwards, it's going to have a minimum, which is the point.
00:30
Like it is the lowest point it can go or the highest point it can go respectively.
00:38
And these maximum and minimum values are called extreme values because they're the furthest extreme that the graph goes.
00:47
It's never going to go lower than here or higher than here.
00:51
It's the extreme value.
00:54
And these extreme values can be found using the vertex formula if your quadratic equation is written in this form.
01:06
Y equals ax squared plus bx plus c.
01:16
And this a, b, and c are just arbitrary constants...
