In fact, talking with the patient may be the most important diagnostic tool the doctor has. The recommendation is that doctors routinely screen all individuals for depression. This screening might occur during a visit for a chronic illness, at an annual wellness visit, or during a pregnancy or postpartum visit.
1 is called the standard form, 2  is called the factored form, where x1 and x2 are the roots of the quadratic function and the solutions of the corresponding quadratic equation. 3  is called the vertex form, where h and k are the x and y coordinates of the vertex, respectively.
Quick Answer. A two-dimensional rectangle has four vertices, and a three-dimensional rectangle has eight. The differences between the two figures are the number of sides and points of intersection. The geometric definition of a vertex is a point in a geometric solid where three or more sides intersect or where two sides intersect in a plane figure. Therefore, a vertex is a corner in a rectangle.
