To show that the function \( f(x) = |\cos x| \) is continuous, we can use the property that the composition of continuous functions is also continuous. Here’s a step-by-step solution: ### Step 1: Identify the functions involved We can express \( f(x) \) as a composition of two functions: - Let \( h(x) = \cos x \) - Let \( g(x) = |x| \) Then, we can write: ...
