The definition of a straight angle is that that any straight angle must measure 180 degrees, Because youre adding the 3 angles of the graph your perfoming and angle addition and as they must measure 180 degrees, the three angles follow the rule of a straight angle.
Answer:
2m+4 is the answer
Step-by-step explanation:
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
