Q. Determine the value of y, if x is −4 .y=∣x∣−5Answer:
Substitute x in function: Substitute the value of x into the function.We are given the function y=∣x∣−5 and the value of x is −4. We need to substitute −4 for x in the function.y=∣−4∣−5
Evaluate absolute value: Evaluate the absolute value of x. The absolute value of −4 is 4 because absolute value measures the distance from zero without considering direction. y=4−5
Perform subtraction: Perform the subtraction.Now we subtract 5 from 4 to find the value of y.y=4−5y=−1
