if the graph of a quadratic opens down work. So that means that we're dealing with a oppa Ravello that looks like this. That's what it means to open down work. Then the weeding coefficient well, weaken right out the equation for a quadratic. So this right here, that's our leading coefficient. And we must have that. It's negative. So eight to less than zero. So this is what we call them a negative number and the vertex of the graph. Well, here's the birth text right over here, and we can see that that's a maximum value, and that's our final answer.
