Which describes the range of the parent absolute value function?
a.{y | y is a real number}
b.{y | y is an integer}
c.{y|y > 0}
d.{y|y < 0}

 The correct option is (C) {y|y > 0}.

Step-by-step explanation:  We are to select the correct option that describes the range of the parent absolute value function.

The parent absolute function is defined as follows:

y = |x|.

Let, x < 0, suppose x = -a, a > 0.

Then,  y = - x = -(-a) = a > 0.

Let x > 0, suppose x = b, b > 0.

Then, y = x = b > 0.

So, whether 'x' is positive (x > 0) or negative (x < 0), y is always positive.

Therefore, the range of the absolute parent function  y = |x| is given by

{y|y > 0}.

Thus, (C) is the correct option.
