f(x) = 3x − 2
f(x) = 3x − 2

f(x) = 4x − 2
f(x) = 4x − 2

−3, 1, 5, 9, 13, 17
−3, 1, 5, 9, 13, 17

an = 3 + (n − 1)(4)
an = 3 + (n − 1)(4)

Answer 1

The second pair of expressions (f(x) = 4x - 2) is UNLIKE the others with respect to the rate of change. The rate of change for the first and third pairs of expressions is 3, while the rate of change for the fourth pair of expressions is 4.
