Explanation:
what you need to do is find the x values for which f(x) is the same as g(x).
you only need to compare the result values in the table.
what functional result values are the same (in the same line) ?
well, -3 and 0.
-3 is the result when x = 0.
and 0 is the result when x = 2.
so, x = 0 and x = 2 are the two correct answers.
for these 2 x values both functions deliver the same results.
