Which of the following is the correct method for solving the equation x3−6=9 for x? (A)Add 6 to both sides of the equation, and then divide both sides of the equation by 3.

(B) Add 6 to both sides of the equation, and then multiply both sides of the equation by 3.

(C)Subtract 6 from both sides of the equation, and then divide both sides of the equation by 3.

(D) Subtract 6 from both sides of the equation, and then multiply both sides of the equation by 3.

I think option (a) is the correct method

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.
