What is the end behavior of the function f(x)= -3x^7+4x^5-14?

Step-by-step explanation:

The degree of the function is odd, so the ends tend in opposite directions. The leading coefficient is negative, so the right end (as x gets large) will tend toward -∞. Then the left end tends toward +∞.

If the degree is even, both ends tend in the same direction. That direction matches the sign of the leading coefficient.
