Answer:
1) 11
2) 15

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
