Answer 1

Answer:

Step-by-step explanation:

F'(x) = (x - 1) (x - 2) (x - 5)

JEE Advanced Question Paper 2019 Maths Paper 2

At x = 1 and x = 5, F'(x) changes from - to +

Therefore, F(x) has two local minima points at x = 1 and x = 5.

F(x) has one local maxima point at x = 2.

Answer: f(x) = (x - 1) (x - 2) (x - 5)

P(λ, 0, 0), Q(0, μ, 1), R(1, 1, r)

Given: \vec {PQ} = k . \vec {PR}  

PQ

​  

=k.  

PR

 

λ/[ λ-1] = - μ/-1 = -1/-r

μ cannot take the values 0 and 1.
