Having a quadratic equation to solve, several steps must be followed in order to find its roots (x-intercepts): Rearrange our equation in a form ax2+bx+c=0 Factor it out if possible into a form a(x−x1)(x−x2
Some functions may also havex-intercepts:for a functiong(x), these are values ofxfor whichg(x) = 0. In other words, anx-intercept is a solution to the equationg(x) = 0. The values ofxthat satisfy this equation are also calledrootsorzeroesof the function. A function ma...
The vertex of a quadratic function is the vertex of the graph of that function. Given a quadratic function in vertex form, f(x) = a(x-h^2)+k, the vertex is located at the point (h,k). It is the point through which the axis of symmetry passes. Knowing how to find the vertex ...
Domain and Range:The domain of a function is the set of all possible inputs {eq}x {/eq} for the function. The range of a function is the set of all possible outputs {eq}y {/eq}. We will use these steps and definitions to find the intercepts, asymptot...
