In which direction does the parabola open? y = –6x2 + 10x + 20 down up left right

1. Down is the correct answer

Step-by-step explanation:

We are given,

The equation of the parabola is .

We know that,

If the equation of parabola .

1. The x is squared, then it opens upwards or downwards.

2. If y is squared, then it opens towards left or right.

Also,

3. If 'a' is positive, then it opens upwards or towards right.

4. If 'a' is negative, then it opens downwards or towards left.

According to the given equation of the parabola, we have,

The variable 'x' is squared and the co-efficient 'a' = -6 is negative.

So, from 1 and 4, we have,

what the question so we can you out
