Answer:

I do not know if this is what you need but this is the table for y = x² + 2x - 4​.

Explanation:

x | y

-1 -1

0 -4

1 -5

2 -4

3 -1

So for the x it's -1, 0, 1, 2, 3 and for y its -1, -4, -5, -4, -1

Direction: Opens Up

Vertex: (1,−5)

Focus: (1,−19/4)

Axis of Symmetry: x=1

Directrix: y=−21/4

Select a few x values, and plug them into the equation to find the corresponding y values. The x values should be selected around the vertex.
