Q. Use the following function rule to find f(7)f(7).\newlinef(x)=9+∣x∣f(x) = 9 + |x|\newlinef(7)=f(7) = _____
  1. Identify function rule and input: Step 11: Identify the function rule and the input value.\newlineWe have the function f(x)=9+∣x∣f(x) = 9 + |x| and we need to find f(7)f(7).
  2. Substitute xx with 77: Step 22: Substitute xx with 77 in the function.\newlinef(7)=9+∣7∣f(7) = 9 + |7|
  3. Calculate absolute value and add: Step 33: Calculate the absolute value of 77 and add it to 99. \newline∣7∣=7|7| = 7, so f(7)=9+7f(7) = 9 + 7
  4. Add numbers to find f(7)f(7): Step 44: Add the numbers to find f(7)f(7).\newlinef(7)=16f(7) = 16
