Question

For second degree polynomial it is seen that the roots are equal. Then what is the relatio
between the Rolles point c and the root x?
(a) c= x2
(b) They are independent
(c) < = x
(d) none of these​

Answer 1

Answer:

d

Explanation:

Given that k = 0 we must rewrite the function to get

y = ax2 + bx

Now differentiating the function yields

y’ = 2ax + b = 0

Equating it to zero we get the Rolle point which is also zero

2a(0) + b = 0

b = 0.
