The interval where the zeros of the function f (x) = 2x + 3x lie is______ .

The interval where the zeros of the function f (x) = 2x + 3x lie is______ .

∵ function f (x) = 2x + 3x is a continuous function on R, and monotonically increasing, f (- 1) = 2-1 + 3 × (- 1) = - 52 < 0, f (0) = 20 + 0 = 1 > 0, f (- 1) f (0) < 0. The interval of the zero point of F (x) = 2x + 3x is (- 1,0), so the answer is (- 1,0)
