Question

over what interval of the domain is function f positive?
a. \\((2, \infty)\\)
b. \\((3, \infty)\\)
c. \\((-\infty, 3)\\)
d. \\((-\infty, 2)\\)

Explanation:

Step1: Identify x-intercept

The graph crosses the x-axis at $x=3$.

Step2: Find positive region

The function is above the x-axis (positive) when $x > 3$, which is the interval $(3, \infty)$.

Answer:

B. $(3, \infty)$
