यदि (f(x)=x-2-2x) और (g(x)=3x-1) हैं, तो ((2f-3g)(x)) क्या होगा?
If (f(x)=x-2-2x) and (g(x)=3x-1), what is ((2f-3g)(x))?
Explanation opens after your attempt
A. \(2x^2-13x+3\)
Concept
(2f-3g=2\(x^2-2x\)-3(3x-1)=2x-2-13x+3). In scalar multiplication, multiply the whole function.
Why this answer is correct
The correct answer is A. \(2x^2-13x+3\). (2f-3g=2\(x^2-2x\)-3(3x-1)=2x-2-13x+3). In scalar multiplication, multiply the whole function.
Exam Tip
(2f-3g=2\(x^2-2x\)-3(3x-1)=2x-2-13x+3)। स्केलर गुणन में पूरे फलन पर गुणा करें।
