Q. Determine the value of y y , if x x is −3-3 .\newliney=x2+3 y=x^{2}+3 \newlineAnswer:
  1. Substitute xx in equation: Substitute the value of xx into the equation.\newlineWe are given x=−3x = -3 and the equation y=x2+3y = x^2 + 3. We need to substitute −3-3 for xx in the equation.\newlineCalculation: y=(−3)2+3y = (-3)^2 + 3
  2. Calculate square of −3-3: Calculate the square of −3-3. When we square −3-3, we get 99 because (−3)×(−3)=9(-3) \times (-3) = 9. Calculation: y=9+3y = 9 + 3
  3. Add 33 to result: Add 33 to the result from Step 22.\newlineNow we add 33 to 99 to find the value of yy.\newlineCalculation: y=9+3=12y = 9 + 3 = 12
