Given f of x is equal to 5 x to the 4th power minus x squared plus 6 x minus 1 What is the limit? limit x to negative 1 of f times x

Because f(x) is a polynomial, it is continuous, so the limit as x approaches −1 equals f(−1). Substituting gives 5(−1)^4 − (−1)^2 + 6(−1) − 1 = 5 − 1 − 6 − 1 = −3. The correct choice is negative 3.
