Mcqs these high school pdf worksheets are based on identifying the correct quadratic function for the given graph.
Identifying characteristics of quadratic functions worksheet. I can identify key characteristics of quadratic functions including axis of symmetry vertex min max y intercept x intercepts domain and range. Y 5 2 x 2 yes yes the second differences are constant. If it is negative find the maximum value.
Graphing quadratic functions identify the following components of each quadratic function. Identify the maximum or minimum value. They are axis of symmetry.
The axis of symmetry of a parabola is a vertical line that divides the parabola into two congruent halves. Each one has model problems worked out step by step practice problems challenge proglems. Name date class quadratic functions identifying key features of quadratic graphs math square by pierceson le 4 5 6.
The maximum or minimum value of a quadratic function is obtained by rewriting the given function in vertex form. Y x2 2x 3 axis of symmetry x b 2a. Identifying quadratic functions tell whether each function is quadratic.
Some of the worksheets for this concept are quadratic functions key features identifying key features unit 2 2 writing and graphing quadratics work properties of quadratic function characteristics of quadratic functions practice work quadratic functions vocabulary graphing quadratics review work name solve each equation with the quadratic quadratic function. X 12 3 4 5 y 03 8 15 24 2. Lt 4 i can apply quadratic functions to model real life situations including quadratic regression models from data.
Use the table of values to graph y x 2 4. Characteristics of quadratic functions find the zeros of each quadratic function from its graph. Each quadratic functions will have some characteristics.
It can be written in the form y ax 2 bx c. From the graph to identify the quadratic function. Lt 8 i can rewrite quadratic equations from standard to vertex and vice versa.
Then graph the function. If you draw the graph for a quadratic equation you can get the shape parabola. If the coefficient of x 2 is positive you should find the minimum value.
You can identify a quadratic expression or second degree expression because it s an expression that has a variable that s squared and no variables with powers higher than 2 in any of the terms. Review the results and record your answers on the worksheets. Xy x 2 4 x y 2 0 2 y 2 2 4 0 y1 1 2 4 3 1 3 0 y 0 2 4 4 0 4 1 y 1 2 4 3 1 3.
Where a is not equal to 0 you can recognize standard quadratic expressions because they follow the form. Quadratic function of the graph. Students should collect the necessary information like zeros y intercept vertex etc.
Point symmetric to y intercept.
