   1. AThe equation of the axis of symmetry is x= -5
   2. Bthe y-intercept is -5
   3. Cthe maximm/minimum value is -5
   4. Dx=0 when y=-5
2. 2state the y-intercept, y=x (squared)+5x+ 4

   1. A5x
   2. B4
   3. Cx(squared)
3. 3state the y-intercept, y=x(squared) + 5x +6

   1. A6
   2. B5x
   3. C7
   4. Dx
4. 4what shape does the graph of a quadratic reltion make?

   1. AA you shape (U)
   2. Bstraight line
   3. CNo shape
5. 5How do you know from a table of values if the relation is quadratic?

   1. Awhen theyre all different numbers
      Example;1,2,3
   2. Bwhen the second diff are the same, and all the numbers are the same.
      Example;2,2,2
