Which set of ordered pairs could be generated by an exponential function?
,- 1/2), (0, 0), (1, 1/2), (2, 1)
b.(–1, –1), (0, 0), (1, 1), (2, 8)
, 1/2), (0, 1), (1, 2), (2, 4)
d.(–1, 1), (0, 0), (1, 1), (2, 4)

What is the next step in the given proof? choose the most logical approach. a. statement: m 1 + m 2 + 2(m 3) = 180° reason: angle addition b. statement: m 1 + m 3 = m 2 + m 3 reason: transitive property of equality c. statement: m 1 = m 2 reason: subtraction property of equality d. statement: m 1 + m 2 = m 2 + m 3 reason: substitution property of equality e. statement: 2(m 1) = m 2 + m 3 reason: substitution property of equality
