    2.

    4.    

Explanation:

1. Start with the pair (0,2)

  Just because it is quick to substitute x = 0 mentally and get the answer by inspection. You will quickly notices that a), b) and c) do not match:

Thus, the answer is d)

2. Try b) y = 2x² for every point

Thus,  b) y=2x² is the correct equation.

3. Since every y is negative the only possible answer is c) y = -x²

Proove it:

4. Try c) y = (1/2)x²

Thus,  c) y = (1/2)x²
