Answer:

B, C, D, and F

Step-by-step explanation:

The graph is an exponential curve rising upwards. By looking at the graph we can tell that the graph is only increasing, it touches the y-axis at 30 and it lies in the 1st quadrant.

So, option A is wrong, as the graph is increasing.

Option B is correct. The point where graph crosses/touches the y-axis is the y-intercept. So the y-intercept is 30.

Option C is correct. As the graph lies in 1st quadrant and is positive over the entire range of values.

Option D is also correct as the graph is increasing over entire range of values.

Option E is incorrect as y-intercept is 30.

Option F is correct. Since the graph is increasing, this means with every passing year the number of dolphins is increasing.

Therefore, the correct options are: B, C, D, and F
