# Local Extrema Count

Calculus Level 4

The graph above depicts the function $$\color{darkred}{f(x)} = |\cos x + 0.5|$$ in the interval $$\color{darkred}0 \leq \color{darkred}x \leq \color{darkred}{10}$$. How many local extrema does the function $$f(x)$$ have if its domain is restricted to $$\color{darkred}0 \leq \color{darkred}x \leq \color{darkred}{10}$$?
