Answer 1

Your function looks more or less like this.

Answer 2

Yes it does.

Answer 3

Use my pic above.

Answer 4

Now see what y-coordinate on the line corresponds to the x-coordinate -2.

Answer 5

You see from the figure above that the point on the line that has x-coordinate -2 has y-coordinate -3. That means the point that has x-coordinate -2 is point (-2, -3).
That also means that f(-2) = -3.
