Directions: Using the integers -9 to 9, at most one time each, fill in the boxes to create a function with the corresponding range and roots.

### Hint

How do each of the values you can choose affect the values of the roots and range?

### Answer

There are many possible answers but all will have a minimum and point upwards including:

y = 1x^2 + 6x + 8

roots: x = -4 and x = -2

range: y ≥ -1

y = 1x^2 + 6x + 5

roots: x = -5 and x = -1

range: y ≥ -4
