<p>The number of solution(s) of the equation <span class="math">f(x) = x^3</span> in <span class="math">[0, 2\pi]</span> be:</p>
Step-by-Step Solution
Key Concept: First determine <span class="math">f(x)</span> from the previous part, then count intersection points with <span class="math">y = x^3</span> on the given interval.
<p><strong>Solution:</strong> From Question 1, determine the explicit form of <span class="math">f(x)</span>. Then solve <span class="math">f(x) = x^3</span> graphically or algebraically in the interval <span class="math">[0, 2\pi]</span> by finding intersection points.</p>
Correct Answer: c
