Q. Determine the value of y y , if x x is −4-4 .\newliney=(x−5)2 y=(x-5)^{2} \newlineAnswer:
  1. Substitute xx value: Substitute the value of xx into the equation.\newlineWe are given x=−4x = -4 and the equation y=(x−5)2y = (x - 5)^{2}. Let's substitute xx with −4-4.\newlineCalculation: y=(−4−5)2y = (-4 - 5)^{2}
  2. Simplify inside parentheses: Simplify the expression inside the parentheses.\newlineWe need to perform the subtraction inside the parentheses before squaring.\newlineCalculation: y=(−9)2y = (-9)^{2}
  3. Square the result: Square the result.\newlineNow we square −9-9 to find the value of yy.\newlineCalculation: y=81y = 81
