The function P(x)=x2 2x−1 is transformed to get I(x)=P(−2x). Which function rule represents I(x)? Responses I(x)=4x2−4x−1 cap i times x is equal to 4 x squared minus 4 x minus 1 I(x)=−4x2−4x 2 cap i times x is equal to negative 4 x squared minus 4 x plus 2 I(x)=−4x2 2x−1 cap i times x is equal to negative 4 x squared plus 2 x minus 1 I(x)=−2x2−4x 2
