Transcribed Image Text:This is a graph of the function \( y = f'(x) \), which represents the derivative of a function \( f(x) \). The graph is plotted on a coordinate grid with the x-axis labeled from 0 to 10 and the y-axis labeled from -2 to 4.
Key features of the graph:
- The curve starts below the x-axis, indicating that the derivative is initially negative.
- Around \( x = 1 \), the curve crosses into positive territory, peaks near \( y = 2.5 \), and then dips slightly before peaking again at approximately \( x = 4.5 \) with a value just over 3.
- The graph then descends rapidly, crossing the x-axis near \( x = 5.5 \), reaching a local minimum below \( y = -1 \) close to \( x = 6.5 \).
- The curve rises again, crossing the x-axis near \( x = 8.5 \), and continues upward.
This graph showcases the behavior of the derivative of a function, indicating changes in the slope of \( f(x) \). Points where \( y = f'(x) = 0 \) correspond to local maxima and minima of \( f(x) \).
Formula Formula A function f(x) attains a local maximum at x=a , if there exists a neighborhood (a−δ,a+δ) of a such that, f(x)<f(a), ∀ x∈(a−δ,a+δ),x≠a f(x)−f(a)<0, ∀ x∈(a−δ,a+δ),x≠a In such case, f(a) attains a local maximum value f(x) at x=a .
