Answer:

<em>4 + 2√3</em><em> </em>

Step-by-step explanation:

x - 2 = √4x

<u><em>Domain: √4x ≥ 0 ⇒ x - 2 ≥ 0 ⇒ x ≥ 2</em></u>

(x - 2)² = (√4x)²

x² - 4x + 4 = 4x

x² - 8x + 4 = 0

D = (- 8)² - 4(1)(4) = 48 = (4√3)²

x_{1} = \frac{8+4\sqrt{3} }{2} =<em> 4 + 2√3</em> ≈ 7.4641

x_{2} = \frac{8-4\sqrt{3} }{2} = 4 - 2√3 ≈ 0.5359 < 2 ⇒ x_{2} is extraneous root

The solid line indicates that the line itself is included in the solutions.  That the shaded area is to the left, or under, the line means that y≤the line.

To find the equation of the line you first find the slope or m using any two points.

m=(y2-y1)/(x2-x1)  in this case you are given (2,-5) and (-2, 3) so

m=(3--5)/(-2-2)

m=8/-4

m=-2

So far for y≤mx+b we have:

y=-2x+b  using either point we can solve for b, I'll use (2,-5)

-5=-2(2)+b

-5=-4+b

-1=b

So the line is:

y=-2x-1  and since y≤ the line:

y≤-2x-1
