To find the maximum or minimum value of a quadratic function start with the general form of the function and combine any similar terms. This is a quadratic function which passes through the x -axis at the. About the quadratic formula.
This is a good question because it goes to the heart of a lot of real math.
Then we plug these coefficients in the formula. If the discriminant is greater than 0 the roots are real and different. So I want to find the zeros. And finally I want to find the equation of the line of symmetry.
