The interval where the zeros of the function f (x) = - 1x + lgx are located is () A. (0,1)B. (1,2)C. (2,3)D. (3,10)

The interval where the zeros of the function f (x) = - 1x + lgx are located is () A. (0,1)B. (1,2)C. (2,3)D. (3,10)

∵ f (2) = - 12 + LG2 < 0f (3) = - 13 + Lg3 > 0 ∵ f (2) · f (3) < 0 ∵ f (x) is in the interval of (2,3), so C is chosen
