Q. Use the following function rule to find f(−72)f(-72).\newlinef(x)=2−x12f(x) = 2 - \frac{x}{12}\newlinef(−72)=f(-72) = _____
  1. Plug in x value: Plug in −72-72 for xx in the function rule.\newlinef(−72)=2−(−72)/12f(-72) = 2 - (-72)/12
  2. Simplify fraction: Simplify the fraction by dividing –72–72 by 1212.f(–72)=2−(–6)f(–72) = 2 − (–6)
  3. Subtract negative number: Subtract the negative number, which is the same as adding its absolute value.\newlinef(–72)=2+6f(\text{–}72) = 2 + 6
  4. Add final answer: Add 22 and 66 to get the final answer.\newlinef(–72)=8f(\text{–}72) = 8
