Answer: both the left and right sides go to +∞
Step-by-step explanation:
End behavior can be determined by two things:
Sign of leading coefficient:
positive: right side goes to +∞
negative: right side goes to -∞
⇒ Leading coefficient of this function is 3 so the right side goes to +∞
Degree (exponent of leading coefficient):
even: both the left and right sides point in the SAME direction
odd: the left and right sides point in OPPOSITE directions
⇒ Degree of this function is 4 so the left side will point in the same direction as the right side.
