How to write a quadratic function with the given zeros? A quadratic has zeros at -5 and -7. Determine the value of k when the quadratic function is in y = a x^2 + k x + c. Algebraically, find the zero(s) of the following quadratic function: f(x) = 5x^2 +17...
Quadratic Functions 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...
What is a quadratic function? 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 by {eq}f(x) {/eq} where {eq}x {/eq} is the independent variable. ...
A quadratic equation is one that consists of a single variable with three terms in the standard form ax2 + bx + c = 0. The uses of...
Roots of a Quadratic Equation 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. ...
