Answer

a. Domain: All real numbers (\mathbb{R}) ### b. Range: All real numbers (\mathbb{R}) Explanation 1. Determine the domain The function y=(x-4)(x+3)(x+5) is a polynomial. Polynomials are defined for all real numbers. 2. Determine the range This is a cubic polynomial with a positive leading coefficient, so it extends to -\infty as x \to -\infty and to \infty as x \to \infty. Thus, the range is all real numbers.

Explanation

1. Determine the domain<br /> The function $y=(x-4)(x+3)(x+5)$ is a polynomial. Polynomials are defined for all real numbers.<br />2. Determine the range<br /> This is a cubic polynomial with a positive leading coefficient, so it extends to $-\infty$ as $x \to -\infty$ and to $\infty$ as $x \to \infty$. Thus, the range is all real numbers.
