Thedomain and range of a functionare the components of afunction. The domain is the set of all the input values of a function and the range is the possible output given by the function. Domain→ Function →Range. If there exists a function f: A →B such that every element of set A ...
Range is all the y-values or dependent variable values that come from the domain. The graphs of quadratic functions are parabolas. This means that the range will be great than or equal to the y-value of the vertex if the parabola is opening up. This y-value of the vertex ...
Start with the graph of a function. Here the function is {eq}y=x^2 {/eq}. Graph of a Parabola The input values are given along the x-axis because the x-values in a function are usually the input values. Notice how the graph extends along the x-axis infinitely in both directions....
And the range for this graph is all real numbers greater than or equal to -3. As you can see, the turning point, or vertex, is part of what determines the range. The other is the direction the parabola opens. If a quadratic function opens up, then the range is all real numbers gre...

Quadratic equations have domains of all real numbers. So the domain is (-∞, ∞). To find the range, we can examine the characteristics of this function. Since this is a quadratic function with degree 2, and the coefficient of the leading term is positive, we have a parab...

A form's quadratic function y=a(x−h)2+k is termed the vertex form of the quadratic function. The vertex of the parabola is at (h,k). The horizontal span of the function is termed the function's domain, and the vertical span is termed the range of the function. ...
