Question 6Find |x| when x15 and x = – 15.o [15= – 15 and 1 – 15| = 15O Both values are 15.o [15= 15 and 1 – 15| = – 15O Both values are – 15.

Answer 1

The absolute value function f(x) = |x| converts its arguments into positive values:

• When x > 0, |x| = x.

,

• When x < 0, |x| = -x.

Then, for x =15, we will get:

`f(15)=|15|=15`

For x = -15 we get:

`f(-15)=|-15|=15`

Answer: Both values are 15.
