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...
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. ...
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 +170x. Algebraically, find the zero(s) of the following quadratic function: h(x) = x^2 - 4x +...
