Hi, I keep submitting the same question regarding Q#3 f to H and landed all 3 different answers on Bartleby. Some experts said the inflection point is (-1,-6) while others got (-1.5,-8.52). Also for the concavity as well. I got one answer that was concave up on (-1.5,0)U(0,inf) and function is concave down on (-inf, -1.5), concave upward on (-1, 0) and concave downward on (- ∞, -1) and (0, ∞), and concave downwards in the interval (−∞, −1) and concave upwards in the interval (−1, ∞). I do not know which was is correct since they're all different. Please help me clarify this issue as it affects my graph. Thank you

Step 1

Since, you have requested for question 3 part f to h, we will solve these parts of the solution.

Step 2

First find the interval for the function **h(x)=x^(5/3)-5x^(2/3)** where the function is concave upward or concave downward.

Step 3

The above derivative of the function is undefined at **x=0**. The graph of the break at the point **x=0** and **x=-**1 into three interval which is as **(-inf, -1)**, **(-1, 0)** and **(0, -inf)**. Now, check the value of second derivative for particular point in the int...
