Answer:

upward

Step-by-step explanation:

The equation showing in the question is actually

[tex]y = x^{2} - 4x - 5[/tex]

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.
