The GREAT QUADRATIC FUNCTION test: Study Guide



The GREAT QUADRATIC FUNCTION Quiz: Study Guide

1. Know that like terms may be combined through addition and subtraction. Remember all exponent properties and distributive property. MOST OF ALL…..watch you Negative operations…..

2. Remember how to factor the GCF from an equation or expression!

3. Use FOIL to multiply a binomial time a binomial.

4. Know how to factor a quadratic equation. Remember to use the zero-product property to solve for the roots.

5. Know how to create a table of values to graph an equation.

6. Know how to find the axis of symmetry. X = -b

2a

7. Remember to plug this in to the equation to find the Vertex Point. Remember the vertex is the maximum or minimum value of the function.

8. Remember that if a < 0 then the graph opens down like a frown. If a > 0 then the graph opens up like a cup.

9. Know how to complete the square to solve for the roots. Remember the roots are the solutions or x-intercepts of the graph.

10. Know that the solutions can be found by solving an equation of x2= by taking the square root of each side to solve for “x”.

11. Know how to re-write an equation using VERTEX FORM.

A= tells if the graph opens up or down, and the horizontal stretch or shrink.

H= when in formula, take opposite h to discover the x-coordinate of the

vertex.

K= when in the formula, k represents the y-coordinate of the vertex.
