Step 1:Let's solve this step by step by analyzing the graph and the piecewise functions.
Step 2:: Examine the graph's characteristics
- The point of transition seems to be at the point $$(1, 3)
- At x = 1, the graph changes from one function to another
Step 3:: Check the left side of the graph (when x \leq 1)
- This matches the first part of the function $$x^3 - 2
- The left side looks like a cubic function
Step 4:: Check the right side of the graph (when x > 1)
- This matches the second part of the function $$x^2 + 4
- The right side looks like a quadratic function
Step 5:: Verify the conditions
- The right side uses $$x^2 + 4$$ when $$x > 1
- The left side uses x^3 - 2 when x \leq 1
Final Answer
The correct answer is **D.** y = \begin{cases} x^3 - 2, & x \leq 1 \ x^2 + 4, & x > 1 \end{cases}
