Q. Given f(x)=5x−3 f(x)=5 x-3 , find f(−5) f(-5) .\newlineAnswer:
  1. Substitute xx with −5-5: To find the value of f(−5)f(-5), we need to substitute xx with −5-5 in the function f(x)=5x−3f(x) = 5x - 3.\newlineCalculation: f(−5)=5(−5)−3f(-5) = 5(-5) - 3
  2. Multiply 55 by −5-5: Now, we multiply 55 by −5-5.\newlineCalculation: 5(−5)=−255(-5) = -25
  3. Subtract 33 from −25-25: Next, we subtract 33 from −25-25.\newlineCalculation: −25−3=−28-25 - 3 = -28
