Q. Determine the value of y y , if x x is −5-5 .\newliney=x2−1 y=x^{2}-1 \newlineAnswer:
  1. Given function: We are given the function y=x2−1y = x^2 - 1 and we need to find the value of yy when xx is −5-5.
  2. Substitute xx: Substitute x=−5x = -5 into the function to find yy.\newliney=(−5)2−1y = (-5)^2 - 1
  3. Calculate square and subtract: Calculate the square of −5-5 and then subtract 11.\newliney=25−1y = 25 - 1
  4. Perform subtraction: Perform the subtraction to find the value of yy.y=24y = 24
