Question

In which direction does the parabola y=x2−4x−5 open?

Answer 1

upward

Explanation:

The equation showing in the question is actually

`y = x^(2) - 4x - 5`

After graphing this equation you can see that the parabola opens up pointing upwards with a vertex of (2, -9) . You can calculate the vertex of the parabola by substituting either y or x with 0 and then solving for the missing variable.
