Answer:

  • d) The domain is x∈R and the range is y∈R

--------------------------------------

Given is the graph of an absolute value function.

It has no domain restrictions, so x can be any real number.

There is a restriction on its range, it has a minimum at y = 0 and the rest of the values are positive real numbers.

It is correctly described in option d).
