quadratic
|
|
In the function y = ax2 + c, if "a" is negative, the parabola opens ___________________.
|
-a: parabola opens downward
|
|
In the same function, if "a" is positive, the parabola has a maximum / minimum value. (Circle one.)
|
+a opens upward:
has minimum value |
|
In the same function, the larger is lal, the wider/narrower the parabola. (Circle one.)
