To find \( f(0) \), simply substitute \( x = 0 \) into the function \( f(x) = 2x - 3 \). Doing the math, we have: \[ f(0) = 2(0) - 3 = 0 - 3 = -3. \] So, \( f(0) = -3 \). Simple as pie! Understanding how to evaluate functions at specific points is crucial in math! It lays the groundwork for topics like graphing, transformations, and even calculus later on. Plus, knowing how to locate outputs for given inputs will help you with real-world scenarios, such as calculating costs, distances, or even projectiles' heights!
