1. The problem is to find the values of $x$ such that $f(x) = 0$. 2. This means we want to solve the equation $$f(x) = 0$$ for $x$. 3. To proceed, we need the explicit form of the function $f(x)$. 4. Once $f(x)$ is known, we set it equal to zero and solve for $x$ using algebraic methods such as factoring, applying the quadratic formula, or other relevant techniques depending on the function type. 5. The solutions to $f(x) = 0$ are called the roots or zeros of the function. 6. Without the explicit function, we cannot find the exact values of $x$. Please provide the function $f(x)$ to continue.
