Find the absolute maximum and minimum values of f(x) = x + (1/x) on the interval [1/2 , 2]
Added by Robert J.
Step 1
Find critical points: To find critical points, we need to find where the derivative of f(x) is equal to zero or undefined. So, we take the derivative of f(x) and set it equal to zero: f'(x) = 1 - 1/x^2 = 0 x^2 = 1 x = ±1 However, x = -1 is not in the interval Show more…
