Answer

Final Answer: The value of the function $f (x) = - \sqrt{- 9 x - 7}$ at $x = - 26$ is approximately $- 15.07$ .

Steps

Step 1 ：The function is given as $f (x) = - \sqrt{- 9 x - 7}$ . We are asked to find the value of the function at $x = - 26$ . To do this, we substitute $x = - 26$ into the function and calculate the result.

Step 2 ：Substitute $x = - 26$ into the function: $f (- 26) = - \sqrt{- 9 (- 26) - 7}$ .

Step 3 ：Simplify the expression inside the square root: $f (- 26) = - \sqrt{227}$ .

Step 4 ：Calculate the square root: $f (- 26) = - 15.066519173319364$ .

Step 5 ：Round the result to two decimal places: $f (- 26) = - 15.07$ .

Step 6 ：Final Answer: The value of the function $f (x) = - \sqrt{- 9 x - 7}$ at $x = - 26$ is approximately $- 15.07$ .
