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.

not only in mathematics, scientific proof also are required in the other field of science. also maths proofs are of particular structure, containing steps and logics. so proving is like doing science, it is science. that's why it is important to prove. 

an inaccurate proof leads to errors, or stating results that are not accurate.  which wil mess the probelm up you dont want this
