QuestionEstimate values for the function $f(x, y)$ based on given level curves for $c=-2,0,2$.
(i) (a) Estimate $f(-1,1)$. (b) Estimate $f(2,1)$. (c) Estimate $f(3,-2.5)$.

Studdy Solution
Therefore, we can estimate that $f(3,-2.5)$ is approximately greater than2.
$$f(3,-2.5) \approx >2$$So, the estimates for the function values at the given points are $f(-,) \approx0$, $f(2,) \approx >2$, and $f(3,-2.5) \approx >2$.
