To find the values of \( x \) such that \( f(x) = 0 \), we need to set the function equal to zero: \[ |2x - 1| - 3 = 0. \] This simplifies to: \[ |2x - 1| = 3. \] Now, we split this into two cases based on the definition of the absolute value. **Case 1:** \( 2x - 1 = 3 \) Solving for \( x \): \[ 2x = 4 \implies x = 2. \] **Case 2:** \( 2x - 1 = -3 \) Solving for \( x \): \[ 2x = -2 \implies x = -1. \] Thus, the values of \( x \) such that \( f(x) = 0 \) are \( x = 2 \) and \( x = -1 \).
