Question

A: -4 < x < -3B: -2 < x < 0C: 0 < x < 2D: none of the above

Answer 1

To know if a function decreases we have to move from left to right along the x-axis.

If we move to the right along the x-axis and the value of y (vertical) decreases, the function decreases.

So, for this graph:

-4-20

So, correct option is A: -4 < x < -3
