Question 81/600 Easy Mathematics Relations and Functions Algebra of real functions Class 11 Level 38

यदि (f(x)=2x^-2+3) और (g(x)=x+5), तो ((f+g)(1)) क्या है?

If (f(x)=2x^-2+3) and (g(x)=x+5), what is ((f+g)(1))?

Explanation opens after your attempt

Correct Answer

C. (11)

Explanation

Simple Explanation

((f+g)(1)=f(1)+g(1)=5+6=11)। पहले (x=1) रखें, फिर जोड़ें। / ((f+g)(1)=f(1)+g(1)=5+6=11). First put (x=1), then add.

Question 82/600 Easy Mathematics Relations and Functions Algebra of real functions Class 11 Level 38

यदि (f(x)=5x^-2+2) और (g(x)=2x^-2-7), तो ((f-g)(x)) क्या होगा?

If (f(x)=5x^-2+2) and (g(x)=2x^-2-7), what will ((f-g)(x)) be?

Explanation opens after your attempt

Correct Answer

C. \(3x^2+9\)

Explanation

Simple Explanation

((f-g)(x)=5x^-2+2-\(2x^2-7\)=3x^-2+9)। ऋण को (-7) पर लगाने से (+7) आता है। / ((f-g)(x)=5x^-2+2-\(2x^2-7\)=3x^-2+9). Applying the minus to (-7) gives (+7).

Question 83/600 Easy Mathematics Relations and Functions Algebra of real functions Class 11 Level 38

यदि (f(x)=x-6) और (g(x)=x), तो ((fg)(x)) क्या है?

If (f(x)=x-6) and (g(x)=x), what is ((fg)(x))?

Explanation opens after your attempt

Correct Answer

A. \(x^2-6x\)

Explanation

Simple Explanation

((fg)(x)=(x-6)x=x^-2-6x)। (x) को दोनों पदों से गुणा करें। / ((fg)(x)=(x-6)x=x^-2-6x). Multiply (x) with both terms.

Question 84/600 Easy Mathematics Relations and Functions Algebra of real functions Class 11 Level 38

यदि (f(x)=4x+11) और (g(x)=x-6), तो ((f+g)(x)) क्या है?

If (f(x)=4x+11) and (g(x)=x-6), what is ((f+g)(x))?

Explanation opens after your attempt

Correct Answer

A. (5x+5)

Explanation

Simple Explanation

((f+g)(x)=4x+11+x-6=5x+5)। (x) पद और स्थिर पद अलग-अलग जोड़ें। / ((f+g)(x)=4x+11+x-6=5x+5). Add (x)-terms and constant terms separately.

Question 85/600 Easy Mathematics Relations and Functions Algebra of real functions Class 11 Level 38

यदि (f(x)=8) और (g(x)=x^-2-3x), तो ((f-g)(x)) क्या है?

If (f(x)=8) and (g(x)=x^-2-3x), what is ((f-g)(x))?

Explanation opens after your attempt

Correct Answer

B. \(8-x^2+3x\)

Explanation

Simple Explanation

((f-g)(x)=8-\(x^2-3x\)=8-x^-2+3x)। घटाने में पूरे (g(x)) के चिह्न बदलते हैं। / ((f-g)(x)=8-\(x^2-3x\)=8-x^-2+3x). In subtraction, signs of the whole (g(x)) change.

Question 86/600 Easy Mathematics Relations and Functions Algebra of real functions Class 11 Level 38

यदि (f(x)=x^-2-25) और (g(x)=x+5), तो (\left\(\frac{f}{g}\right\)(x)) का सरल रूप क्या है, जहाँ \(x\neq-5\)?

If (f(x)=x^-2-25) and (g(x)=x+5), what is the simplified form of (\left\(\frac{f}{g}\right\)(x)), where \(x\neq-5\)?

Explanation opens after your attempt

Correct Answer

A. (x-5)

Explanation

Simple Explanation

(\frac{x^-2-25}{x+5}=\frac{(x-5)(x+5)}{x+5}=x-5)। शर्त \(x\neq-5\) साथ रखें। / (\frac{x^-2-25}{x+5}=\frac{(x-5)(x+5)}{x+5}=x-5). Keep the condition \(x\neq-5\).

Question 87/600 Easy Mathematics Relations and Functions Algebra of real functions Class 11 Level 38

यदि (f(x)=x^-2-4x+4) और (g(x)=x-2), तो (\left\(\frac{f}{g}\right\)(x)) क्या है, जहाँ \(x\neq2\)?

If (f(x)=x^-2-4x+4) and (g(x)=x-2), what is (\left\(\frac{f}{g}\right\)(x)), where \(x\neq2\)?

Explanation opens after your attempt

Correct Answer

B. (x-2)

Explanation

Simple Explanation

क्योंकि (x^-2-4x+4=(x-2)²), इसलिए भागफल (x-2) है। (x=2) को डोमेन से हटाएँ। / Since (x^-2-4x+4=(x-2)²), the quotient is (x-2). Remove (x=2) from the domain.

Question 88/600 Easy Mathematics Relations and Functions Algebra of real functions Class 11 Level 38

यदि (f(x)=x-1) और (g(x)=x+10), तो ((f+g)(1)) क्या होगा?

If (f(x)=x-1) and (g(x)=x+10), what will ((f+g)(1)) be?

Explanation opens after your attempt

Correct Answer

B. (11)

Explanation

Simple Explanation

((f+g)(1)=f(1)+g(1)=0+11=11)। शून्य मान को जोड़ में शामिल करें। / ((f+g)(1)=f(1)+g(1)=0+11=11). Include the zero value in the sum.

Question 89/600 Easy Mathematics Relations and Functions Algebra of real functions Class 11 Level 38

यदि (f(x)=5x) और (g(x)=x+1), तो ((fg)(3)) का मान क्या है?

If (f(x)=5x) and (g(x)=x+1), what is the value of ((fg)(3))?

Explanation opens after your attempt

Correct Answer

B. (60)

Explanation

Simple Explanation

((fg)(3)=f(3)g(3)=15\cdot4=60)। (fg) का अर्थ फलनों का गुणन है। / ((fg)(3)=f(3)g(3)=15\cdot4=60). (fg) means product of functions.

Question 90/600 Easy Mathematics Relations and Functions Algebra of real functions Class 11 Level 38

यदि (f(x)=x^-2-4) और (g(x)=x^-2+4), तो ((f+g)(x)) क्या है?

If (f(x)=x^-2-4) and (g(x)=x^-2+4), what is ((f+g)(x))?

Explanation opens after your attempt

Correct Answer

A. \(2x^2\)

Explanation

Simple Explanation

((f+g)(x)=x^-2-4+x^-2+4=2x^-2)। विपरीत स्थिर पद कट जाते हैं। / ((f+g)(x)=x^-2-4+x^-2+4=2x^-2). Opposite constant terms cancel out.
