यदि \(f:\mathbb{R}\to\mathbb{R}\), (f(x)=7-2x), तो (f) की एकैकी प्रकृति क्या है?

If \(f:\mathbb{R}\to\mathbb{R}\), (f(x)=7-2x), what is the one-one nature of (f)?

Correct Answer

A. एकैकी हैOne-one

Step 1

Concept

Assume (f(a)=f(b)).

Step 2

Why this answer is correct

(7-2a=7-2b) gives (a=b).

Step 3

Exam Tip

A decreasing linear function is also one-one because it gives distinct outputs for distinct inputs. चरण 1: (f(a)=f(b)) मानें। चरण 2: (7-2a=7-2b) से (a=b) मिलता है। चरण 3: घटता रैखिक फलन भी एकैकी होता है, क्योंकि वह हर आगत को अलग निर्गत देता है।
