Q. Determine the value of y, if x is −10 .y=∣x∣−4Answer:
Substitute x in function: Substitute the value of x into the function.We are given the function y=∣x∣−4 and the value of x is −10. We need to substitute −10 for x in the function.y=∣−10∣−4
Evaluate absolute value: Evaluate the absolute value of x. The absolute value of −10 is 10, because the absolute value of a number is always non-negative. y=10−4
Perform subtraction: Perform the subtraction.Now we subtract 4 from 10 to find the value of y.y=10−4y=6
