On July 7, HRD Minister Ramesh Pokhriyal announced a major CBSE syllabus reduction with 30% of the syllabus slashed for the year 2020-21 for classes 9 to 12 because of the reduction in classroom teaching time due to the Covid-19 pandemic and lockdown.

The function is said to be "one one" if every element of set A have unique image in set B One one function is also known as" injective " The function is said to be "many one" if two or more elements of set A has same image in set B The function is said to be "onto" if every element of set B has pre image in set A It is also known as "surjective" If function f is both one one and onto then the function is called " bijective "

The minimum value of the polynomial x(x+1)(x+2)(x+3) is:

Posted by Harsh Mishra 3 years, 11 months ago

CBSE > Class 12 > Mathematics

1 answers

Yogita Ingle 3 years, 11 months ago

P(x) = x (x + 1)(x + 2)(x + 3)

=> P(x) = x(x + 3)(x + 1)(x + 2)

=> P(x) = (x² + 3x )(x² + 3x + 2)

=> P(x) = (x² + 3x )² + 2(x² + 3x)

Let say y = x² + 3x

p(y) = y² + 2y

p'(y) = 2y + 2

=> y = - 1

p''(y) = 2 > 0

=> y = -1 will give minimum value

p(y) = y² + 2y

=> P(-1) = (-1)² + 2(-1)

=> P(-1) = 1 - 2

=> P(-1) = - 1

Hence minimum value of the polynomial x (x + 1)(x + 2)(x + 3) is - 1

What is the nature of V-I graph of Ohm's law

Posted by Rabina Toijam 3 years, 11 months ago

CBSE > Class 12 > Mathematics

1 answers

Gaurav Seth 3 years, 11 months ago

A linear VI curve has a constant slope and hence a constant resistance. Carbon resistors and metals obey Ohm's law and have constant resistance. This means that the V-I curve is a straight line passing through the origin. An electronic component may exhibit linear characteristics only in a particular region.

Shruti Kumari 3 years, 11 months ago

Given Relation R={(1,1),(2,2),(3,3)} Reflexive: If a relation has {(a,b)} as its element, then it should also have {(a,a),(b,b)} as its elements too. Symmetric: If a relation has (a,b) as its element, then it should also have {(b,a)} as its element too. Transitive: If a relation has {(a,b),(b,c)} as its elements, then it should also have {(a,c)} as its element too. Now, the given relation satisfies all these three properties. Therefore, its an equivalence relation.
