Domain And Range Of Linear And Quadratic Functions Worksheet 1 Determine the vertex for each quadratic function by completing the square State if the vertex is a maximum or a minimum 3 An electronics store sells an average of 60 entertainment systems per month at an average of 800 more than the cost price
The general form of a quadratic function presents the function in the form f x ax2 bx c where a b and c are real numbers and a 0 If a 0 the parabola opens upward If a 0 the parabola opens downward We can use the general form of a parabola to find the equation for the axis of symmetry For many functions the domain and range can be determined from a graph An understanding of toolkit functions can be used to find the domain and range of related functions A piecewise function is described by more than one formula A piecewise function can be graphed using each algebraic formula on its assigned subdomain

Worksheet Practice PACKET 12 I can use the discriminant to determine the number and type of solutions zeros 1 I can identify a function as quadratic given a table equation or graph 2 I can determine the appropriate domain and range of a quadratic equation or event 3 I can identify the minimum or maximum and zeros of a function with a Example PageIndex 5 Find the Domain and Range of a Quadratic Function Find the domain and range of f x 5x 2 9x 1 Solution As with any quadratic function the domain is all real numbers Because a is negative the parabola opens downward and has a maximum value The maximum value must be determined
Domain and Range Worksheets This compilation of domain and range worksheet pdfs provides 8th grade and high school students with ample practice in determining the domain or the set of possible input values x and range the resultant or output values y using a variety of exercises with ordered pairs presented on graphs and in table format Finding Domain and Range from Graphs Another way to identify the domain and range of functions is by using graphs Because the domain refers to the set of possible input values the domain of a graph consists of all the input values shown on the x axis The range is the set of possible output values which are shown on the y axis Keep in mind

These Algebra 1 Domain and Range Worksheets will produce problems for finding the domain and range of graphed sets You can select the types of things graphed as well as whether the sheet should ask if each graph is a function or not These Domain and Range Worksheets are a good resource for students in the 9th Grade through the 12th Grade For every polynomial function such as quadratic functions for example the domain is all real numbers If f x a x h k then if the parabola is opening upwards i e a 0 the range is y k if the parabola is opening downwards i e a 0 the range is y k
Explore math with our beautiful free online graphing calculator Graph functions plot points visualize algebraic equations add sliders animate graphs and more Solution method 1 The graphical approach It turns out graphs are really useful in studying the range of a function Fortunately we are pretty skilled at graphing quadratic functions Here is the graph of y f x Now it s clearly visible that y 9 is not a possible output since the graph never intersects the line y 9
