Consider the function f(x) = 2x(1/2) - (√17) /(17) x on the interval [11,27]. Find the absolute extrema for the function on the given interval. Express your answer as an ordered pair (x,f(x) ) .
a) (11, 2√11 - (√17) /(17) * 11)
b) (27, 2√27 - (√17) /(17) * 27)
c) (11, 2√27 - (√17) /(17) * 11)
d) (27, 2√11 - (√17) /(17) * 27)
