Question
The variation of $w$ against $x$ is shown in the figure for selected values of parameter $y$.
The graph indicates that $w$
The correct answer is
increases nonlinearly with $x$, but decreases nonlinearly with $y$.
The given graph shows the relationship between w and x for selected values of the parameter y. Let's analyze the graph to determine the nature of these relationships.
- Observe the graph for w against x for different values of y. The curves are not straight lines, indicating a nonlinear relationship between w and x.
- Notice how the curves are steeply increasing as x increases, supporting the idea that w increases nonlinearly with x.
- As the parameter y increases (moving from y=25 to y=200), the curves shift downward. This suggests that w decreases with increasing y.
- The downward shift of curves as y increases is not linear. Thus, w decreases nonlinearly with y.
Conclusion: Based on the analysis, the graph indicates that w increases nonlinearly with x and decreases nonlinearly with y. Therefore, the correct option is:
increases nonlinearly with x, but decreases nonlinearly with y.
