Assignment 3: Quadratic Functions

For the following functions make a table from x=-4 to x=+4 and then a graph:

1.  y = 2x^2 + 3

2.  y = -4x^2 + 3

3. y = -3x^2 + 5

4. y = 2x^2 - 4

5. y = x^2 - 2x

6. y = -2x^2 + 3x

7. y = 3x^2 - 4x + 2

8. y = 4x^2 + 2x - 2

9. Describe how you will know whether the quadratic funtion will open up or open down?

10.  How can you determine the location of the y intersect from the equation?
