Question

1. State whether f (x) = x^-1 has a minimum value, maximum value, or neither on the following intervals. Select all that apply.

(a) (0, 3)

(b) (1, 3)

(c) [1, 3)

Need Help.

Answer 1

f(x)=1/x
f'(x)=-1/x²
Since f'(x) does not have a real root, it does not have a maximum, nor a minimum.
Can you take it from here?
