Q. Use the following function rule to find f(12)f(12).\newlinef(x)=12x+8f(x) = \frac{12}{x} + 8\newlinef(12)=f(12) = _____
  1. Substitute xx in function: Substitute 1212 for xx in the function f(x)=12x+8f(x) = \frac{12}{x} + 8.\newlinef(12)=1212+8f(12) = \frac{12}{12} + 8
  2. Simplify fraction: Simplify the fraction 1212\frac{12}{12} to get 11.\newlinef(12)=1+8f(12) = 1 + 8
  3. Add to find value: Add 11 and 88 to find the value of f(12)f(12).f(12)=9f(12) = 9
