Answer:

Step-by-step explanation:

let f(x) = y and rearrange making x the subject

y = $\frac{x+2}{7}$ ( multiply both sides by 7 to clear the fraction )

7y = x + 2 ( subtract 2 from both sides )

7y - 2 = x

Change y back into terms of x with x the inverse function, that is

p(x) = 7x - 2

If you plug in some values for x, you can graph it on the plane.

When x = 0.

$\sqrt{0} = 0$

When x = 1

$\sqrt{1} = 1$

When x = 4

$\sqrt{4} = 2$

$\sqrt{9} = 3$

Now plot the points and draw a graph through the points.

So, the last option is the answer.
