Beyond the Answer
As \( x \rightarrow -\infty, f(x) \rightarrow +\infty \). This is because the leading term \( -x^8 \) is negative, and since it's raised to an even power, the output will positive when \( x \) is a large negative number. As \( x \rightarrow \infty, f(x) \rightarrow -\infty \). Here, when \( x \) takes on large positive values, the term \( -x^8 \) becomes vastly negative due to the negative coefficient and the even exponent, leading \( f(x) \) to trend downwards.
