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.
To do this choose any other point on the parabola and plug in for x and y. I am going to choose the point (1,0) for this example which mean I will plug 1 in for x and 0 in for y. Now that we know a we can plug everything into vertex form. Final Answer for vertex form! Now letâs find factored form! The terms and are the x values of the root, so we must identify the roots. Looking at the graph we can see the roots (or x-intercepts) are the points (1,0) and (3,0).
