let's keep in mind that, in the II Quadrant, cosine is negative and sine, is positive.
cosine is adjacent/hypotenuse, however the hypotenuse is simply a radius unit, and thus is never negative, so in the -(2/3) the negative must be the numerator, -2.
Given:
Polynomial is .
Term is added in the given polynomial.
To find:
The end behavior of new polynomial.
Solution:
Let, .
New polynomial is
Highest power of x is 6 which is even and leading coefficient is negative. So,
Both ends of the graph will approach negative infinity.
Therefore, the correct option is A.
