Q. Use the following function rule to find f(12) f(12) .\newlinef(x)=∣−1+x∣f(x)=|-1+x|\newlinef(12)=□f(12) = \square
  1. Plug in 1212: First, plug in 1212 for xx in the function rule.\newlinef(12)=∣−1+12∣f(12) = \left| -1 + 12 \right|
  2. Addition inside absolute value: Now, do the addition inside the absolute value. ∣−1+12∣=∣11∣|-1 + 12| = |11|
  3. Find absolute value: Finally, find the absolute value of 1111. ∣11∣=11|11| = 11
