Answer:

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.
