Prove that g is not one-to-one using the definition of a one-to-one function. g(x)=x²-x www Select the correct choice below and fill in the answer box(es) to complete your choice. OA. There exist two numbers 1 and 1 such that 1 # -1, and Thus, g is not one-to-one. g(1) = g(-1) = H OB. There exist two numbers 1 and -1 such that 1 # -1, and g(1) = g(-1) = are different. Thus, g is not one-to-one. and
