Q. Determine the value of y, if x is −11 .y=x2−4Answer:
Given function substitution: We are given the function y=x2−4 and need to find the value of y when x is −11. To do this, we substitute x with −11 in the equation and calculate the value of y. y=(−11)2−4
Calculate square of −11: Now we calculate the square of −11.(−11)2=121
Subtract 4 and find y: Next, we subtract 4 from the result of the square of −11 to find y.y=121−4
Perform final subtraction: Perform the subtraction to get the final value of y.y=117
