Given graph is :

We have to graphically estimate the global extrema of f on:

$$\begin{gathered} \left(a\right)\left(-1,1\right)\left(b\right)[2,∞)\left(c\right)[-2,1) \\ \left(d\right)[0,2]\left(e\right)(1,∞)\left(f\right)\left(-∞,∞\right) \end{gathered}$$

It is seen that the function f has a global minimum at x=-0 as the function is decreased up to that point and the function f has no global maximum.

It is seen that the function f has a global minimum at x=-0 as the function is decreased up to that point and the function f has no global maximum.

It is seen that the function f has a global minimum at x=-0 as the function is decreased up to that point and the function f has no global maximum.
