1. The question asks: What is the easiest function to solve? 2. In mathematics, the easiest functions to solve are typically linear functions because they have the form $$y = mx + b$$ where $$m$$ and $$b$$ are constants. 3. Linear functions are easy to solve because they involve only first-degree terms and can be solved by simple algebraic manipulation. 4. For example, to solve $$y = 2x + 3$$ for $$x$$ when $$y = 7$$: $$7 = 2x + 3$$ 5. Subtract 3 from both sides: $$7 - 3 = 2x + \cancel{3} - \cancel{3}$$ $$4 = 2x$$ 6. Divide both sides by 2: $$\frac{4}{\cancel{2}} = \frac{2x}{\cancel{2}}$$ $$2 = x$$ 7. So, the solution is $$x = 2$$. This shows why linear functions are the easiest to solve: they require only basic arithmetic and algebraic steps.
