1. We are asked to solve the equation \( f(x) = 0 \). 2. To find \( x \) such that \( f(x) = 0 \), we set the function equal to zero and solve for \( x \). 3. Without the explicit form of \( f(x) \) given in this part, let's assume you have the function expression from previous parts. Plug that expression into \( f(x) = 0 \) and solve the resulting equation using algebraic methods such as factoring, applying the quadratic formula, or other applicable techniques. 4. The solution set will be the set of all \( x \) values where the function equals zero, written exactly (not decimal approximations). If you provide the explicit function \( f(x) \), I can show detailed step-by-step solving. Otherwise, the general procedure is to solve the equation \( f(x) = 0 \) exactly.
