Q. Use the following function rule to find f(49)f(49).\newlinef(x)=5+xf(x) = 5 + \sqrt{x}\newlinef(49)=f(49) = _____
  1. Identify Function and Input: Identify the function and the input value.\newlineWe are given the function f(x)=5+xf(x) = 5 + \sqrt{x} and we need to find the value of f(49)f(49).
  2. Substitute Input into Function: Substitute the input value into the function.\newlineTo find f(49)f(49), we substitute 4949 for xx in the function:\newlinef(49)=5+49f(49) = 5 + \sqrt{49}
  3. Calculate Square Root: Calculate the square root of the input value.\newlineThe square root of 4949 is 77, so we have:\newlinef(49)=5+7f(49) = 5 + 7
  4. Add Numbers: Add the numbers to find the final value.\newlineNow we add 55 and 77 to get the value of f(49)f(49):\newlinef(49)=12f(49) = 12
