Answer:
f(x)→−∞ as x→−∞ and f(x)→−∞ as x→∞
Step-by-step explanation:
Since the leading term of the polynomial (the term in a polynomial which contains the highest power of the variable) is −x4, then the degree is 4, i.e. even, and the leading coefficient is −1, i.e. negative.
This means that f(x)→−∞ as x→−∞ and f(x)→−∞ as x→∞.
