The answer is C
By plugging in 1 1/2 to the equation, I know x does not equal 3 1/2, so A is incorrect.
When I look at the table, I see that when x=1, f(x) = 2, and when x=2, f(x) = 5. Because 1 1/2 is in between 1 and 2, than your answer should be in between 2 and 5. B is correct in saying that x > 0, but C is the best answer because it is more specific, saying that x is in between 2 and 5.
