Plugging into the original equation gives: C = Y1 - AX1^2 - BX1 This all looks horrible, but we have the values for Y1, Y2, Y3, X1, X2, and X3 so we just plug them in. The example does that to find A, B, and C. It then graphs the function so you can see it passes th...
For my assignment on quadratic functions, I have to find the equation (the the form of ax^2+bx+c) for a table of values? You stuck a question mark on the end - do you not know? Please type out the exact problem statement ... do you have a table of values given to you and ...
I would like to know how to find the equation of a quadratic function from its graph, including when it does not cut thex-axis. Thanks. Modeling This is a good question because it goes to the heart of a lot of "real" math. Often we have a set of data points from observati...
Multiply the Step 2 result by -1 to find the x-coordinate of the minimum or maximum. In 2x^2+3x-5, you would multiply 0.75 by -1 to get -0.75 as the x-coordinate. Step 4 Plug in the x-coordinate into the expression to find the y-coordinate of the minimum or maximum. You would...

To find a quadratic from its zeroes and some other point (that is, some point off the x-axis), you convert the zeroes to factors, to get x2 + bx + c. Then you plug that extra point into the general quadratic equation, y = a(x2 + bx + c), where a is the unknown numerical...
It might, however, be very difficult to find such a factorization. For example: x^2 -6x + 7 Then the roots are 3 - sqrt 2 and 3 + sqrt 2. These are not so easy to find. The ABC Formula Another way to find the roots of a quadratic function. This is an easy method that anyon...
