The solution of an equality is the set of values of the unknown for which both members are equal. In this case, the values of x for which the two functions are equal.
The table shows three values of x for which the outputs of both f(x) and g(x) are equal. Those values of x are the solutions of the equality f(x) = g(x).
Such points are:
(-2,4) and (-1,2).
Realize that means that for x = -2 and x = -1, the values of both functions f(x) and g(x) are the same.
So, according to the table, x = -2, and x = -1 are solutions to f(x) = g(x)
