From the graph of the function, determine the domain and the range. A. Domain: [- 4, 4 ] Range: [ 0, 4 ]
B. Domain: [0, 4] Range: [0, 4]
C. Domain: [0, 4] Range: [-4, 4]
D. Domain: [-4, 4) Range: (0, 4)

If m∠abc = 70°, what is m∠abd? justify your reasoning.  using the addition property of equality, 40 + 70 = 110, so m∠abd = 110°.  using the subtraction property of equality, 70 − 30 = 40, so m∠abd = 30°.  using the angle addition postulate, 40 + m∠abd = 70. so, m∠abd = 30° using the subtraction property of equality.  using the angle addition postulate, 40 + 70 = m∠abd. so, m∠abd = 110° using the addition property of equality.
