Answer:
The ___a_ value of the quadratic function determines whether the parabola opens upward or downward.
Answer:
The 'a' value.
Step-by-step explanation:
The general quadradic equation is:
[tex]ax^2 + bx + c; \text{ } a\neq 0[/tex]
If the value of a is greater than 0, then the parabola would open upward. If the value of a is less than 0, then the parabola would open downward.
