QUESTION:
23–30. Locating critical points
a. Find the critical points of the following functions on the domain or on the given interval.
b. Use a graphing utility to determine whether each critical point corresponds to a local minimum, local maximum, or neither.
\(f(x)=x-\tan ^{-1} x\)
ANSWER:STEP_BY_STEP SOLUTION Step-1 Let f be a continuous function defined on an open interval containing a number ‘c’.The number ‘c’ is critical value ( or critical number ). If f (c) = 0 1 1 or f (c) is undefined. A critical point on that graph of f has the form (c,f(c)). Step_2 The given function is; f(x) = x - tan (x) .Here the first function is algebraic function an
