Let's analyze the graph and answer the questions based on it.

The graph shows the function $y = f(x)$. You are asked to:

a) Beräkna $f(2)$
This asks you to find the value of the function $f(x)$ at $x = 2$. Look at the graph where $x = 2$ and find the corresponding $y$-value.

From the graph:

• At $x = 2$, the value of $f(x)$ is $y = 4$.

Thus, $f(2) = 4$.

b) Lösa ekvationen $f(x) = 14$
This asks for the values of $x$ where $f(x) = 14$. Look at the graph and find the $x$-values where the $y$-coordinate equals 14.

From the graph:

• $f(x) = 14$ occurs at two points: $x = -12$ and $x = 12$.

Thus, the solutions to $f(x) = 14$ are $x = -12$ and $x = 12$.

Would you like further explanation or have any questions?

Here are five related questions you can explore:

1. What is the value of $f(-10)$?
2. What is the value of $f(0)$?
3. Solve the equation $f(x) = 10$.
4. At which $x$-values does the graph have local maxima or minima?
5. Determine the intervals where the function is increasing or decreasing.

Tip: Always ensure to carefully analyze the scale of both the x-axis and y-axis when reading off values from a graph.
