Let's analyze the graph of the function $f(x)$ from the image you uploaded.

1. Evaluate $f(3)$:

To evaluate $f(3)$, we find the value of the function when $x = 3$. From the graph, locate the point where $x = 3$. By following the vertical line upwards, we see that the function value at $x = 3$ corresponds to $f(3) = 4$.

Thus, $f(3) = 4.$

2. Solve $f(x) = 3$:

To solve $f(x) = 3$, we look for the $x$-value where the function's output is 3. By finding the horizontal line at $f(x) = 3$ on the graph, it intersects the curve at around $x \approx 2$.

Therefore, the solution is approximately: $x \approx 2.$

Would you like further details on these calculations, or any additional questions?

Here are some relative questions to explore further:

1. How can you use the graph to estimate other values of $f(x)$?
2. What are the key features of the function in the graph, such as intercepts and asymptotes?
3. Can we determine the behavior of $f(x)$ as $x$ approaches positive and negative infinity?
4. What type of function does the graph likely represent (e.g., exponential, quadratic)?
5. How would the solution change if $f(x) = 5$ instead of $f(x) = 3$?

Tip: When interpreting graphs, always carefully check the scales on both the x- and y-axes for accurate evaluation of values!
