Q. Determine the value of y, if x is 10 .y=x2−11Answer:
Substitute x into equation: Substitute the value of x into the equation.We have the equation y=x2−11 and we need to find the value of y when x is 10.Substitute x=10 into the equation.y=102−11
Calculate square of 10: Calculate the square of 10. 102=100Now, substitute this value back into the equation.y=100−11
Subtract 11 from 100: Subtract 11 from 100 to find the value of y.y=100−11y=89
