Standard form: f(x)=ax2+bx+c Factored form:f(x)=a(x+r)(x+s) Vertex form: f(x)=a(x−h)2+k What is the difference between a quadratic equation and a quadratic function? A quadratic equation is polynomial equation of degree 2. It has the form: ax2+bx+c=0 where a ...
Standard form: f(x) = ax2 + bx + c, where a ≠ 0. Vertex form: f(x) = a(x - h)2 + k, where a ≠ 0 and (h, k) is the vertex of the parabola representing the quadratic function. Intercept form: f(x) = a(x - p)(x - q), where a ≠ 0 and (p, 0) and (q...

A function of the form f(x) = ax2+ bx + c, where a ≠ 0 is called a quadratic function in variable x. Similar to afunction, a quadratic expression also has a domain and a range value. What Does Quadratic Mean in a Quadratic Expression?
Example:Write thequadratic functionf given by f(x) = -2 x2+ 4 x + 1 in standard form and find the vertex of the graph. Solution given function f(x) = -2 x2+ 4x + 1 factor -2 out f(x) = -2(x2- 2 x) + 1 We now divide the coefficient of x which is -2by 2 and ...
