Here is my question hope you see it.

This is simplifying square root expressions. It is hard for me to describe the procedure on my computer but I can tell you the answer.

The answer is choice 2. Always remind yourself to simplify and to group same square roots. 

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.
