यदि (f(x)=3x-2) और (g(x)=x+4) हों, तो ((fg)(1)) क्या होगा?
If (f(x)=3x-2) and (g(x)=x+4), what is ((fg)(1))?
Explanation opens after your attempt
A. (5)
Concept
(f(1)=1) and (g(1)=5), so ((fg)(1)=5). In a product function, multiply the values.
Why this answer is correct
The correct answer is A. (5). (f(1)=1) and (g(1)=5), so ((fg)(1)=5). In a product function, multiply the values.
Exam Tip
(f(1)=1) और (g(1)=5), इसलिए ((fg)(1)=5)। गुणनफल फलन में मानों को गुणा करें।
