Q. Determine the value of y, if x is 9.y=x2−8Answer:
Identify Function and x Value: Identify the given function and the value of x for which we need to find y. We are given the function y=x2−8 and we need to find the value of y when x is 9.
Substitute x into Function: Substitute the value of x into the function to find y. We substitute x=9 into the function y=x2−8. So, y=92−8.
Calculate y: Calculate the square of 9 and subtract 8 from it to find y.92=81, so y=81−8.
Perform Subtraction: Perform the subtraction to find the final value of y.y=81−8=73.
