3. h(x) = x2 + 3x – 1 evaluate h(-3)
4. f(x) = x3 +5x evaluate f(9)
5. f(x) = -4x - 3 evaluate f(-10)
6. f(x) = x3 + 7x2 + 1 evaluate f(0)

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.
