What is a Parabola? If you graph a linear function, you get a line. If you graph a quadratic function, you get something called a parabola. A parabola tends to look like a smile or a frown, depending on the function. Check out this tutorial and learn about parabolas!Further...
function: A function is a relation between two sets which maps one element to one and only one element in another set. It is represented byf(x)wherexis the independent variable. Answer and Explanation:1 A quadratic function or a quadratic polynomial is a polynomial expression with the highest...

What are the values of a, b, and c in the quadratic equation 4x^2 - 3x - 7 = 0? What is the formula for solving quadratic equations? What is the general form of quadratic equation? Which are the solutions of x in the quadratic equation x^2 = 7x + 4?
Let p ( x ) = 0 be a quadratic equation. Then the zeros of the polynomial p ( x ) are called the roots of the equation p ( x ) = 0. Thus x = α is a root of p ( x ) = 0 if and only if p ( α ) = 0.
