All boxes Below is the graph of the derivative \( f'(x) \) of a function defined on the interval \( (0,8) \). You can click on the graph to see a larger version in a separate window.Refer to the graph to answer each of the following questions. For part (A), use interval notation to report your answer. (If needed, you use \( U \) for the union symbol.)---**(A)** For what values of \( x \) in \( (0,8) \) is \( f(x) \) concave down? (If the function is not concave down anywhere, enter "\(\{\}\)" without the quotation marks.)*Answer:*---**(B)** Find all values of \( x \) in \( (0,8) \) is where \( f(x) \) has an inflection point, and list them (separated by commas) in the box below. (If there are no inflection points, enter \(-1000\).)*Inflection Points:*---**Graph Description:**The graph shown is a small section plotted in the first quadrant with variable units along both axes. It features a curve depicting the derivative's values over the interval \( (0,8) \). The graph has critical points where the curve changes its direction. The image is a graph displaying a trigonometric function, likely a sine wave, plotted on a Cartesian coordinate system.### Description of the Graph:- **Axes:** - The x-axis is labeled with numerical values starting at 0 and extends to 8. - The y-axis ranges from approximately -3 to 3. The labeling isn’t fully visible but seems consistent with typical sine wave values.- **Wave:** - The wave is oscillating with clear peaks and troughs. - The cycle starts slightly above the y-axis and descends to a trough before rising to a peak. - The wave completes at least one full cycle of oscillation from about 0 to 8 on the x-axis.### Characteristics:- **Amplitude:** - The amplitude seems to be about 2, measured from the centerline to the peak or trough.- **Period:** - The period appears to be about 4 units on the x-axis, indicating the length of one full cycle.- **Phase Shift:** - The wave appears to start at about 0 on the x-axis, suggesting no phase shift.### Educational Context:This graph could be used to explain fundamental properties of trigonometric functions, like amplitude, period, and phase shift. It serves as an example for analyzing wave patterns in physics or mathematics curricula, offering a visual representation of periodic functions.
