Answer:
if the x^2 part is negative then the parabola opens upward, but if it's negative then it will open downwards.
Step-by-step explanation:
Given a quadratic equation, the way to determine whether the parabola opens up or down is that;
Opens up is leading coefficient is greater than zero and opens down if leading coefficient is less than zero.
The general form of a quadratic equation is;
y = ax² + bx + c
Where c is the y-intercept
If the leading coefficient which is the value of a is greater than zero, then the parabola will open upwards.
