Let's analyze the graph based on the three tasks:

i) Funktion f nollakohdat (Zero points of the function f):

The zero points are where the function $f(x) = 0$. This occurs where the curve intersects the x-axis. Based on the graph, the function has zero points at: $x = -3 \quad \text{and} \quad x = 1$

ii) Funktion f arvo, kun $x = -2$ (Value of the function when $x = -2$):

At $x = -2$, we can observe the y-coordinate on the graph, which is around 2. Therefore: $f(-2) = 2$

iii) Ne muuttujan arvot, joilla funktio f saa arvon -2 (The values of $x$ where the function $f(x) = -2$):

We need to find where the graph intersects the line $y = -2$. Based on the graph, the function takes the value $-2$ at two points: $x = -1 \quad \text{and} \quad x = 0$

Summary:

1. Zero points: $x = -3$ and $x = 1$
2. $f(-2) = 2$
3. $f(x) = -2$ at $x = -1$ and $x = 0$

Would you like further details on any of these?

Here are 5 related questions to explore further:

1. What is the maximum value of the function based on the graph?
2. What is the minimum value of the function?
3. What is the behavior of the function as $x \to \infty$?
4. Can you derive the equation of the function based on the graph?
5. How would you interpret the slope at various points on this graph?

Tip:

When analyzing graphs, always look at where the function intersects key lines (such as the x-axis and y-axis) for important values like zeros and y-intercepts.
