<PRE><B>Question 396995</B>
 how do you write a quadratic function in standard form whose graph passes through the given points: (2,7) (3,2) and (5,4)?
-------------
Use ax^2+bx+c = y
You need to find a,b, and c.
---
Substitute each of the points into the 
quadratic form to get three equations
with three variables.
---
Solve the system and find the formula.
