Question 29

A landscape architect is designing a section of a path. The elevation $h\,$ of the path (in meters) relative to a reference level is modeled by the function

\frac{1}{12}x^4 + \sin x + 5

for $−π≤x≤π-\pi \le x \le \pi$ , where $x\,$ represents the horizontal distance in meters from a marker.

Determine whether the curve with equation $y = h (x)$ has a point of inflection at the point where $x = 0$ . Fully justify your answer.
