This is a question about quadratic functions.
00:07
The question asks us to find the quadratic equation whose graph has this vertex and passes through this point.
00:21
And we want to find this quadratic equation in vertex form, which is sometimes called the standard form.
00:31
Though one should be careful since sometimes this other form is referred to as the standard form.
00:41
And that's a different form with a different or well with the same value of a actually different values of b and c then we have for p and q and so i refer to this form as the vertex form and rightfully so since the point so since uh given this equation with p here and q here the vertex is the point whose x coordinate is and y coordinate is q.
01:19
Okay, so since we want to find this quadratic equation, we want to find a and p and q, though since we're given the vertex, we don't have to find p and q, we are already given these coordinates of the vertex.
01:38
The x coordinate p is 5 over 2, or sorry negative 5 or 2, and the y coordinate is 0...
