Solve the Inequality: Find X Where f(x) < 0

To solve for when f(x) < 0 on the graph, we follow these steps:

• Step 1: Locate the x-intercepts, where the curve intersects the x-axis. These intercepts are $x = 2$ and $x = 8$.

• Step 2: Analyze the sections determined by these intercepts. The graph is below the x-axis to the left of $x = 2$ and to the right of $x = 8$.

By visually inspecting the graph, it is evident that:

• The function $f(x)$ is below the x-axis (i.e., negative) for x < 2 and x > 8 .

Therefore, the solution to the problem is that the graph of the function is negative for x > 8 or x < 2 .
