Q. Given f(x)=−x−2 f(x)=-x-2 , find f(−1) f(-1) .\newlineAnswer:
  1. Identify Function and Value: Identify the function and the value to be substituted into the function.\newlineThe function given is f(x)=−x−2f(x) = -x - 2, and we need to find the value of f(−1)f(-1).
  2. Substitute xx with −1-1: Substitute xx with −1-1 in the function f(x)=−x−2f(x) = -x - 2.\newlinef(−1)=−(−1)−2f(-1) = -(-1) - 2
  3. Simplify Expression: Simplify the expression by performing the operations. f(−1)=1−2f(-1) = 1 - 2
  4. Complete Calculation: Complete the calculation to find the value of f(−1)f(-1).f(−1)=−1f(-1) = -1
