Solution:

Notice that for each function, they are simply in the form
f(k(x)), where
k(x) is some function of
x. More specifically,
g(x)=f(x-2), h(x)=f(2x), \text{ and } j(x) = f(x^2).

Thus, because the Interval of Convergence of
f(x) is
-3 < x < 3, the Interval of Convergence of
g(x) should be
-3 < x-2 < 3 \implies -1 < x < 5.

Similarly, the Interval of Convergence of
h(x) is
-3 < 2x < 3 \implies -\frac32 < x < \frac32.

Finally, the Interval of Convergence of
j(x) should be
-3 < x^2 < 3 \implies 0 < x < √(3).
