Question 3
4 / -1

Let f(x) be a polynomial function of second degree. If f(1) = f(-1) and a, b, c are in A.P. then f ′(a), f ′(b) and f ′(c) are in

A
A.P.

B
G.P.

C
H.P.

D
arithmetic geometric progression

Solution

Let f(x) = px² + qx + r

f(1) = f(-1) gives q = 0.

∴ f(x) = px² + r

f ′(x) = 2px

f ′(1) = 2ap, f ′(2) = 2bp, f ′(3) = 2cp

a, b, c are in A.P.

∴ 2a, 2b, 2c are in A.P.

∴ 2ap, 2bp, 2cp are in A.P.

∴ f ′(a), f ′(b), f ′(c) are in A.P.
