Question
Find the maximum and minimum value, if any, of the following function given by h(x) = x + 1, x ∈ (−1, 1)
Advertisements
Solution
We have, h(x) = x + 1, 1, -1 < x < 1.
-1 < x < 1
= -1 + 1 < x + 1 < 1 + 1
= 0 < x + 1 < 2
Here, range of f = (0, 2)
∴ f has neither a maximum nor a minimum value.

Complete the following activity to divide 84 into two parts such that the product of one part and square of the other is maximum.
Solution: Let one part be x. Then the other part is 84 - x
Letf (x) = x2 (84 - x) = 84x2 - x3
∴ f'(x) = `square`
and f''(x) = `square`
For extreme values, f'(x) = 0
∴ x = `square "or" square`
f(x) attains maximum at x = `square`
Hence, the two parts of 84 are 56 and 28.
