Q. Determine the value of y, if x is −1 .y=∣x∣−12Answer:
Substitute x into function: Substitute the value of x into the function.We are given the function y=∣x∣−12 and we need to find the value of y when x is −1.Substitute x=−1 into the function.y=∣(−1)∣−12
Evaluate absolute value: Evaluate the absolute value of x. The absolute value of −1 is 1, because the absolute value of a number is the distance of that number from 0 on the number line, regardless of direction. y=∣(−1)∣−12y=1−12
Perform subtraction: Perform the subtraction.Now we subtract 12 from 1 to find the value of y.y=1−12y=−11
