Answer 1

Answer:

The graph is a parabola with vertex (0 , -2)

Equation: y = x² -2

For x = -2, y = (-2)² -2 ⇒  y = 4 - 2  ⇒  y = 2

For x = -1, y = (-1)² -2 ⇒  y = 1 - 2  ⇒  y = -1

For x = 0, y = (0)² -2 ⇒  y = 0 - 2  ⇒  y = -2

For x = 1, y = (1)² -2 ⇒  y = 1 - 2  ⇒  y = -1

For x = 2, y = (2)² -2 ⇒  y = 4 - 2  ⇒  y = 2
