analyze the graph of the function f(x) to complete the statement. f(x)<0 over (-∞, -3) and what other…

Explanation:

Step1: Understand function values below 0

We need to find where the graph of $y = f(x)$ is below the $x$-axis (since $f(x)<0$ means the $y -$ values of the function are negative).

Step2: Analyze the graph

The graph of $y = f(x)$ is below the $x$-axis for $x\in(-\infty,- 3)$ and also for $x\in(-1.1,0.9)$. We can see from the $x -$ intercepts and the shape of the curve that between $x=-1.1$ and $x = 0.9$, the $y$-values of the function are negative.

Answer:

$(-1.1,0.9)$
