Exercise 10.2 Page No: 10.16

1. If f is defined by f (x) = x2, find f’ (2).

Solution: 2. If f is defined by f (x) = x2 – 4x + 7, show that f’ (5) = 2 f’ (7/2)

Solution:  Hence the proof.

3. Show that the derivative of the function f is given by f (x) = 2x3 – 9x2 + 12 x + 9, at x = 1 and x = 2 are equal.

Solution:

We are given with a polynomial function f(x) = 2x3 – 9x2 + 12x + 9, and we have 4. If for the function Ø (x) = λ x2 + 7x – 4, Ø’ (5) = 97, find λ.

Solution:

We have to find the value of λ given in the real function and we are given with the differentiability of the function f(x) = λx2 + 7x – 4 at x = 5 which is f ‘(5) = 97, so we will adopt the same process but with a little variation. 5. If f (x) = x3 + 7x2 + 8x – 9, find f’ (4).

Solution:

We are given with a polynomial function f(x) = x3 + 7x2 + 8x – 9, and we have to find whether it is derivable at x = 4 or not,  6. Find the derivative of the function f defined by f (x) = mx + c at x = 0.

Solution:

We are given with a polynomial function f(x) = mx + c, and we have to find whether it is derivable at x = 0 or not, This is the derivative of a function at x = 0, and also this is the derivative of this function at every value of x.
