Short Answer TypeFind the absolute maximum value and the absolute minimum value of the following functions in the given intervals:
Long Answer TypeFind the absolute maximum and minimum values of the function f given by
f (x) = cos2x + sinx, x ∊ [0, 
].
Find the points at which the function f given by f (x) = (x – 2)4 (x + 1 )3 has
(i) local maxima (ii) local minima (iii) point of inflexion .
Here, 
When x < 2 slightly, 
When x > 2 slightly, 
When x < -1 slightly f ' (x) = (-) (+) (-) = +ve
When x > -1 slightly, f ' (x) = (-) (+) (-) = +ve
at x = -1, f ' (x) does not change sign
x = -1 is a point of inflexion.
