Q. Use the following function rule to find f(115)f(115).\newlinef(x)=4x99f(x) = 4\sqrt{x - 99}\newlinef(115)=f(115) = _____
  1. Identify Function and Input: Identify the function and the input value.\newlineWe are given the function f(x)=4x99f(x) = 4\sqrt{x - 99} and we need to find the value of f(115)f(115).
  2. Substitute Input into Function: Substitute the input value into the function.\newlineTo find f(115)f(115), we substitute 115115 for xx in the function:\newlinef(115)=411599f(115) = 4\sqrt{115 - 99}
  3. Simplify Expression Inside Square Root: Simplify the expression inside the square root. Calculate the value inside the square root: 11599=16115 - 99 = 16
  4. Apply Square Root: Apply the square root to the simplified expression.\newlineNow take the square root of 1616:\newline16=4\sqrt{16} = 4
  5. Multiply by 44: Multiply the result by 44 as per the function rule.\newlineFinally, multiply the square root by 44 to find f(115)f(115):\newlinef(115)=4×4f(115) = 4 \times 4
  6. Calculate Final Answer: Calculate the final answer. f(115)=16f(115) = 16
