1. **State the problem:** Evaluate the expression inside the brackets and then write the function $y = x^3$ multiplied by that evaluated value. 2. **Evaluate the bracketed expression:** The expression is $0^4 - 20^3 + 0^2$. 3. **Calculate each term:** - $0^4 = 0$ - $20^3 = 20 \times 20 \times 20 = 8000$ - $0^2 = 0$ 4. **Substitute and simplify:** $$0 - 8000 + 0 = -8000$$ 5. **Write the final function:** Since the bracket evaluates to $-8000$, the function is $$y = -8000 \times x^3 = -8000x^3$$ **Final answer:** $$y = -8000x^3$$
