If (f(x)=x+2) and (g(x)=3x), what is ((f+g)(x))?
A. (4x+2)
योग में समान (x) पद जोड़े जाते हैं, इसलिए ((f+g)(x)=x+2+3x=4x+2)। परीक्षा में पहले कोष्ठक खोलें। / In addition, like (x) terms are added, so ((f+g)(x)=x+2+3x=4x+2). In exams, open brackets first.

If (f(x)=5x-1) and (g(x)=2x+4), find ((f-g)(x)).
A. (3x-5)
((f-g)(x)=(5x-1)-(2x+4)=3x-5)। घटाने में दूसरे फलन के सभी चिह्न बदलें। / ((f-g)(x)=(5x-1)-(2x+4)=3x-5). In subtraction, change every sign of the second function.

If (f(x)=x+1) and (g(x)=x-1), what is ((fg)(x))?
A. \(x^2-1\)
गुणन में ((fg)(x)=f(x)g(x)), इसलिए ((x+1)(x-1)=x-2-1)। पहचान \(a^2-b^2\) याद रखें। / In multiplication, ((fg)(x)=f(x)g(x)), so ((x+1)(x-1)=x-2-1). Remember the identity \(a^2-b^2\).

If (f(x)=2x+6) and (g(x)=2), what is (\left\(\frac{f}{g}\right\)(x))?
A. (x+3)
भाग में (\left\(\frac{f}{g}\right\)(x)=\frac{2x+6}{2}=x+3)। हर शून्य नहीं होना चाहिए। / In division, (\left\(\frac{f}{g}\right\)(x)=\frac{2x+6}{2}=x+3). The denominator must not be zero.

If (f(x)=x-2) and (g(x)=4), what is the value of ((f+g)(2))?
A. (8)
((f+g)(2)=f(2)+g(2)=4+4=8)। पहले फलन जोड़ें या सीधे मान रखें। / ((f+g)(2)=f(2)+g(2)=4+4=8). You may add functions first or substitute directly.

If (f(x)=3x) and (g(x)=x+5), find the value of ((f-g)(1)).
A. (-3)
((f-g)(1)=f(1)-g(1)=3-6=-3)। मान रखने से पहले सही क्रम देखें। / ((f-g)(1)=f(1)-g(1)=3-6=-3). Check the correct order before substituting.

If (f(x)=x+2) and (g(x)=x+3), what is ((fg)(1))?
A. (12)
((fg)(1)=f(1)g(1)=3\times4=12)। गुणन फलन में मानों का गुणा करें। / ((fg)(1)=f(1)g(1)=3\times4=12). In product of functions, multiply the values.

If (f(x)=x-2-4) and (g(x)=x-2), what is the value of (\left\(\frac{f}{g}\right\)(3))?
A. (5)
(\left\(\frac{f}{g}\right\)(3)=\frac{9-4}{3-2}=5)। भाग में हर का मान शून्य नहीं होना चाहिए। / (\left\(\frac{f}{g}\right\)(3)=\frac{9-4}{3-2}=5). In division, the denominator value must not be zero.

If (f(x)=x-2+1) and (g(x)=2x), then ((f+g)(x)) is equal to which expression?
A. \(x^2+2x+1\)
((f+g)(x)=x-2+1+2x=x-2+2x+1)। पदों को घटते घात क्रम में लिखना अच्छा रहता है। / ((f+g)(x)=x-2+1+2x=x-2+2x+1). Writing terms in descending powers is a good exam habit.

If (f(x)=4x+7) and (g(x)=x-3), what is ((f-g)(x))?
A. (3x+10)
((f-g)(x)=(4x+7)-(x-3)=3x+10)। ऋण चिह्न को पूरे कोष्ठक पर लगाएँ। / ((f-g)(x)=(4x+7)-(x-3)=3x+10). Apply the minus sign to the whole bracket.
