There are 8 Power Point files in this zip folder. 3 are student study guides, 4 are assignment files and 1 is an intro to form conversions. A brief description of each:
The Intro is a 56 slide presentation. The emphasis is converting forms:
1. Vertex form to standard form
2. Factored form to standard form
3. Standard form to factored form
4. Standard form to vertex form
Standard to vertex form is done by completing the square and the -b/2a method. 10 formative assessment problems are included in the file with solutions.
Study Guide file #1 is a 1 page printable study guide that gives characteristics and examples of the following forms of a quadratic function:
A. Vertex Form of a Quadratic Function
B. Intercept or Factored Form of a Quadratic Function
C. Standard form of a Quadratic Function
Study Guide file #2 is a 1 page printable study guide with the 10 possible transformations of parent function y=x^2. The parent function is displayed on a graph with the individual transformations. These transformations are:
1. Shift left in y=(x+2)^2
2. Shift right in y=(x-2)^2
3. Shift up in y=x^2+2
4. Shift down in y=x^2-2
5. Vertical stretch in y=2x^2
6. Vertical shrink in y=(1/2)x^2
7. Horizontal stretch in y=(x/2)^2
8. Horizontal shrink in y=(2x)^2
9. Vertical reflection in y=-x^2
10. Horizontal reflection in y=(-x)^2
Study Guide #3 is a companion to the 56 slide Intro to form conversions. The examples from this file are compiled on 1 page for easy printing.
Assignment file #1 is a 24 question multiple choice assignment. The students are asked to identify quadratic forms, identify the vertex on a grid in vertex form, identify an x intercept in intercept form and to identify the y intercept in standard form. It is also available on Socrative.com. The socrative share number is included in the file. On paper it is on 1 page for easy printing.
Assignment file #2 is a 1 page assignment consisting of 20 multiple choice questions about these types of quadratic functions. It is on 1 page for easy printing.
Assignment file #3 is 2 assignments. Each is on 1 page for easy printing. Each is 4 problems. The student is given a parabola in all 3 forms (vertex, standard and factored forms). The student is asked to identify, without a calculator:
1. The vertex
2. The x intercept(s)
3. The y intercept
4. The axis of symmetry
5. The direction
6. If the parabola is more narrow or wide than y=x^2
The student is also asked to sketch a graph of the function.
Assignment file #4 is a 4 problem graphing assignment. The student is given 1 parabolic equation ion standard for, 2 in vertex form and 1 in intercept form. The student is asked to identify the vertex, intercept of axes, domain, range, axis of symmetry and if the vertex is a minimum or maximum. A 40x40 grid is provided for graphing. It is on 2 pages for printing.
