Q. Determine the value of y, if x is 11 .y=x2−7Answer:
Identify Function and Value: Identify the given function and the value of x for which we need to find y. We are given the function y=x2−7 and we need to find the value of y when x is 11.
Substitute Value into Function: Substitute the value of x into the function to find y. We substitute x=11 into the function y=x2−7. So, y=112−7.
Calculate Square of 11: Calculate the square of 11.112 equals 121.
Subtract 7: Subtract 7 from the result of the square of 11 to find y.y=121−7.
Perform Final Subtraction: Perform the subtraction to get the final value of y.y=114.
