Answer:
Last option: Square both sides of the equation in step 1 to eliminate the square root.
Step-by-step explanation:
The error is in the process of subtracting 3 from both sides, since +3 is inside the root.
In order to be able to operate with the terms that are inside the root, we need to eliminate the root, and for that we need to square both sides of the equal sign.

Answer: Option a.
Step-by-step explanation:
  1. You have the following parent function given in the problem above:
 f(x)=x³ (This is the simplest form. We need to translate it 3 units left and 2 units down)
 2. If you take the parent function and make y=f(x+3), then you have:
  (The function is shifted 3 units left on the x-axis).
 (The function is shifted 3 units left on the x-axis).
 3. Then you if you make y=f(x+3)-2, as following, you obtain:
  (The function is shifted 2 units down on the y-axis).
  (The function is shifted 2 units down on the y-axis).
 4. Therefore, that is how you obtain the final function.
 The answer is the graph shown in the option a.

Answer:
   17,500
Step-by-step explanation:
The problem can be written as a proportion:
   hits/revenue = 1000/(£2) = x/(£35)
Multiplying by £35 gives ...
   x = 1000(35/2) = 35000/2 = 17,500
17500 hits are required for revenue of £35.
