Q. Use the following function rule to find f(86)f(86).\newlinef(x)=2−86xf(x) = 2 - \frac{86}{x}\newlinef(86)=f(86) = _____
  1. Substitute xx in f(x)f(x): Substitute 8686 for xx in f(x)=2−86xf(x) = 2 - \frac{86}{x}.\newlinef(86)=2−8686f(86) = 2 - \frac{86}{86}
  2. Simplify the fraction: Simplify the fraction 8686\frac{86}{86} to get 11.\newlinef(86)=2−1f(86) = 2 - 1
  3. Find the value of f(86)f(86): Subtract 11 from 22 to find the value of f(86)f(86).\newlinef(86)=1f(86) = 1
