WebMay 22, 2015 · Since x 2 2 ≥ 2 for x ≥ 2 and x ≤ − 2, your function will increase on those intervals. So, you need to only consider − 2 ≤ x ≤ 2. Both cos ( x) and x 2 2 are even functions. This allows us to only consider − 2 ≤ x ≤ 0. On this interval cos ( x) is an increasing function. Thus cos ( x) − 1 is also increasing. In addition x 2 2 is increasing.
