Q. Determine the value of y, if x is −8 .y=x2+8Answer:
Identify Equation and Value: Identify the given equation and the value to substitute.We are given the equation y=x2+8 and we need to find the value of y when x is −8.
Substitute Value into Equation: Substitute the value of x into the equation.Substitute x=−8 into the equation y=x2+8 to find y.y=(−8)2+8
Calculate Square of −8: Calculate the square of −8.Calculate (−8)2.(−8)2=64
Add 8 to Result: Add 8 to the result from Step 3.Add 8 to 64 to find the value of y.y=64+8y=72
