Question

the graph of the pressure exerted on an eel moving underwater is shown in the figure find the interval along which the second derivative of the pressure is negative

Answer 1

Answer:

$(1.5,2.5)$

Step-by-step explanation:

The second derivative tells whether the curve is concave up or concave down at that point. If the second derivative is positive at a point, the graph is bending upwards at that point. Similarly, if the second derivative is negative, the graph is concave down.

Therefore, for the given graph, the second derivate of the pressure is negative on the interval:

$(1.5,2.5)$
