Correct answers only ! i cannot retake subtract.

Since there's a common denominator, you can go straight into subtracting,

so for the top,  x^2 + 8x - x^2 -2x + 6 will simplify to -6x -6 which with the bottom can be reduced (dividing everything by 3) to 2x - 2/x^2 + x

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.
