Final answer:

The end behavior of the graph of q(x) is as x approaches positive or negative infinity, q(x) approaches negative infinity.

Step-by-step explanation:

The end behavior of a polynomial function can be determined by examining the leading term of the polynomial. In this case, the leading term is -2x^8. Since the degree of the leading term is even and the leading coefficient is negative, the end behavior of the graph of q(x) is as follows:

  • As x approaches positive infinity, q(x) approaches negative infinity.
  • As x approaches negative infinity, q(x) also approaches negative infinity.

Therefore, the correct answer is (Choice B) As x→∞, q(x)→-∞, and as x→−∞, q(x)→∞.
