From the graph provided, we are tasked with finding the $x$-values where $f(x) = 0$. These points are the x-intercepts, where the curve crosses the x-axis.

Based on the graph:

• The curve crosses the x-axis at three points.
  1. Approximately at $x = -7$
  2. Approximately at $x = 0$
  3. Approximately at $x = 6$

Thus, when $f(x) = 0$, the approximate values of $x$ are: $x \approx -7, 0, 6$

Would you like further details or have any questions?

Here are 5 related questions you might consider:

1. What are the maximum and minimum points on the graph?
2. How can you determine the intervals of increase and decrease from the graph?
3. What is the range of the function shown in the graph?
4. How do we find the points of inflection from this graph?
5. How can we estimate the derivative at specific points along the curve?

Tip: The x-intercepts are the points where a function changes sign, often providing valuable insight into the behavior of the function in different regions.
