PLZ help me Select ALL the correct answers.The graph below represents the number of dolphins in a dolphin sanctuary.A.The graph is decreasing over the interval (0,∞ )B.The graph has a y-intercept of 30C.The graph is positive over the interval (0, ∞)D.The graph is increasing over the interval (0, ∞)E.The graph has a y-intercept of 185F.As the number of years increases, the number of dolphins in the sanctuary increases

Answer:B, C, D, and FStep-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
