1. The question asks whether the function is increasing (rastúca) or decreasing (klesajúca). 2. To determine this, we need the function or its graph to analyze its behavior. 3. Since no specific function or graph is provided, we cannot definitively say if it is increasing or decreasing. 4. If you provide the function or graph, I can help determine if it is increasing or decreasing by checking the sign of its derivative or slope.
