Answer:

Step-by-step explanation:
It is required to find the parent function of the given graph.
Since, we know that,
Range of the functions,
and
is [-1,1].
<em>So, the given graph cannot be obtained from the functions
and
.</em>
Also, we know,
Range of the functions,
and
is
.
<em>Thus, the given graph cannot be obtained from the functions
and
.</em>
So, we are left with the functions,
and
.
Moreover, as 
But, in the graph, function is going to infinity when x= 0.
<em>Thus, the graph cannot be obtained from
.</em>
Hence, the parent function is
.
