How do you know if a parabola has a minimum?

When ‘a’ is positive there is a minimum

When ‘a’ is negative there is a minimum

When all the numbers in the equation are negative there is a minimum

When all the numbers in the equation are positive there is a minimum

How can you tell whether a parabola opens up or opens down by looking at the equation?

The value of "a" tells you the direction of the opening.

The vertex tells you the direction of the opening
