1. **Problem statement:** For the function $f(x) = 9 - 2x$ with domain $x = \{-3, 0, 1, 7\}$, find the range values. 2. **Formula and rules:** To find the range, substitute each domain value into the function and calculate $f(x)$. 3. **Calculations:** - For $x = -3$: $$f(-3) = 9 - 2(-3) = 9 + 6 = 15$$ - For $x = 0$: $$f(0) = 9 - 2(0) = 9$$ - For $x = 1$: $$f(1) = 9 - 2(1) = 9 - 2 = 7$$ - For $x = 7$: $$f(7) = 9 - 2(7) = 9 - 14 = -5$$ 4. **Answer:** The range values are $\{15, 9, 7, -5\}$. This completes the solution for the first problem.
