X:  The x is represented with a circle and a x in the middle.

9:  The 9 is represented with the squares on the left side that have the ones.  The whole left side is devoted to the 9.

3:  The 3 is represented with the right side.  Aka the three circles.

X + 2:  The x + 2 is represented with one circle that has 1 x and 2 1's.

3(X + 2):  The 3(x + 2) is represented by the whole right side.

Equal Sign:  The equal sign is the top that connects both the left and right side.

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.
