plug in x = 1 and x = 2 into the expression what are the values of P(x)/ if there is a change of sign then you have the required interval

The options they give are A (0,0.5) B (0.5, 1) C (1, 1.5) D (1.5, 2) E (2, 2.5) Im not sure what you mean by sign changes? I thought that was used to determine the max number of zeros
