Based on the question, "k" is the vertical movement of the graph from the parent function. The parent function f(x) = x³ has the graph below.
As we compare the original graph above and the graph on the question, we can see that the graph is move 2 units to the left and 3 units downwards.
Since "k" represents the vertical movement of the parent graph and we see that the parent graph is moved 3 units downward, then the value of "k" is -3. (Option 1)
