Answer:
When x goes to negative infinity, y goes to positive infinity; when x goes to positive infinity, y goes to positive infinity.
Step-by-step explanation:
The largest power of this function is 4, since the term is x^4. This means that the graph of the function will closely resemble a parabola.
Since the coefficient of x^4 is positive, that means that the parabola will resemble a smile.
The end behavior is when x goes to negative infinity, y goes to positive infinity; when x goes to positive infinity, y goes to positive infinity.
Hope this helps!
