Answer:
The last option
Explanation:
The end behaviour can be determined from the term of highest degree, that is the leading term in standard form.
• Odd degree, positive leading coefficient
Here the leading term is 5x³ ← odd degree, positive leading coefficient
Hence
f(x) → + ∞ as x → + ∞ and f(x) → - ∞ as x → - ∞
This is the last option in the list given.
