Q. Given f(x)=−5x−5 f(x)=-5 x-5 , find f(2) f(2) .\newlineAnswer:
  1. Identify Function and Input: Identify the function and the input value.\newlineWe are given the function f(x)=−5x−5f(x) = -5x - 5 and we need to find the value of f(2)f(2).
  2. Substitute Input into Function: Substitute the input value into the function.\newlineTo find f(2)f(2), we substitute xx with 22 in the function f(x)=−5x−5f(x) = -5x - 5.\newlineSo, f(2)=−5(2)−5f(2) = -5(2) - 5.
  3. Perform Multiplication: Perform the multiplication.\newlineNow we calculate −5×2-5 \times 2.\newlinef(2)=−5×2−5=−10−5f(2) = -5 \times 2 - 5 = -10 - 5.
  4. Perform Addition: Perform the addition.\newlineNow we add −10-10 and −5-5.\newlinef(2)=−10−5=−15f(2) = -10 - 5 = -15.
