Question

find the second and third derivatives of the following functions-
(i) ax^2 + bx + c (ii) 2x/1-x (iii) 6x^4 - 3x - 4 (iv) 1+x/1-x(x is not equal to 1)

Answer 1

1) Second Derivative : 2a
Third Derivative = 0

2)Second Derivative=4/(1-x)^3
Third Derivative=12/(1-x)^4

3)Second Derivative=72x^2
Third Derivative=144x

4)Second derivative=4/(1-x)^3
Third Derivative=12/(1-x)^4
