Answer:

I just took the test and got 100%...

1. C

2. B

3. C

4. Option 1(-2,-2) is a local minimum......Option 3(4,4) is the global maximum.

Good luck with the rest of the semester :)

  From the graph attached, Options (1) and (3) represent the correct points (local minimum and global maximum).

    If there are multiple peaks and troughs in the graph of a function, highest peak will be the global maximum and lowest point will be the global minimum.

 From the graph attached,

(4, 4) is the highest but the lowest point is in the infinity.

Therefore, (4, 4) will be the global maximum and no global minimum.

Other point in the trough (-2, -2) will be local minimum and the points on  peaks (0, 2) and (-4, 3) will be local maximum.

  Therefore, Options (1) and (3) will be the correct options.
