It appears that the provided text contains a mix of mathematical expressions and some unrelated elements. Let's focus on the mathematical expressions and solve them step by step.1. **Expression: ** This expression seems to be incorrect as written. Let's correct it: Simplifying the right-hand side: So, the corrected function is: 2. **Expression: ** This expression is also unclear. Let's rewrite it in a more standard form: Simplifying the left-hand side: Solving for : 3. **Expression: ** This expression can be simplified: Distributing the negative sign: Simplifying further: So, the corrected and simplified expressions are:1. \( f(x) = 3 \)2. 3. \( -(x + 1) + 3 = -x + 2 \)
