Q. Use the following function rule to find f(49)f(49).\newlinef(x)=8+xf(x) = 8 + \sqrt{x}\newlinef(49)=f(49) = _____
  1. Identify Function & Input: Identify the function and the input value.\newlineWe are given the function f(x)=8+xf(x) = 8 + \sqrt{x} and we need to find the value of f(49)f(49).
  2. Substitute Input: Substitute the input value into the function.\newlineTo find f(49)f(49), we substitute 4949 for xx in the function:\newlinef(49)=8+49f(49) = 8 + \sqrt{49}
  3. Calculate Square Root: Calculate the square root of the input value.\newlineThe square root of 4949 is 77, since 7×7=497 \times 7 = 49.
  4. Add to Constant Term: Add the square root to the constant term in the function.\newlineNow we add the square root of 4949 to the constant term 88:\newlinef(49)=8+7f(49) = 8 + 7
  5. Perform Final Addition: Perform the addition to find the final result. f(49)=15f(49) = 15
