A. एकैकी हैOne-one
Concept
मान लें (f(a)=f(b))। / Assume (f(a)=f(b)).
Why this answer is correct
\(\frac{3a-1}{5}=\frac{3b-1}{5}\) से (3a-1=3b-1), इसलिए (a=b)। / From \(\frac{3a-1}{5}=\frac{3b-1}{5}\), we get (3a-1=3b-1), so (a=b).
Exam Tip
हर में स्थिर गैर-शून्य संख्या हो तो रैखिक एकैकीपन नहीं बदलता। / A non-zero constant denominator does not change the one-one nature of a linear function.
