Relative Extrema Definition OA function fis said to have a relative maximum at xo if there is an open interval containing xo on which fo)is the largest value,i.e.fxo)x)for all x in the interval OA function f is said to have a relative minimum at xo if there is an open interval containing xo on which f(xo)is the smallest value,i.e.fxo)x)for all x in the interval Relative Extrema ⚫Definition A function f is said to have a relative maximum at x0 if there is an open interval containing x0 on which f(x0 ) is the largest value, i.e. f(x0 )≥f(x) for all x in the interval A function f is said to have a relative minimum at x0 if there is an open interval containing x0 on which f(x0 ) is the smallest value, i.e. f(x0 )≤f(x) for all x in the interval
