Find the maximum or minimum values, if any, without using derivatives, of the function:
.

min. value = 4

Since the square of any no. Is positive, the given function has no maximum value.

The minimum value exists when the quantity (5x-1)²=0

Therefore, minimum value=4

Find the points on the curve , where the tangent to the curve is parallel to the chord joining (1, −2) and (2, 2).

If , where c > 0, show that , where 0 < a < c < b.
