యొక్క పరిధి
f(x)అన్ని ఉంది y-ఒక సంఖ్య ఉన్న విలువల x తో y=f(x)
సాధన:
ప్రమేయ పరిధిని కనుగొనడానికి \(f(x) = \frac {|x|}{x}, x \neq 0\), మొదట ప్రమేయంను విభజించండి.
\(\rm f(x) = \frac {x}{x} , x>0\)
\(\rm f(x) = \frac {-x}{x} , x<0\)
పరిధి మనకు తెలుసు is అన్నీ y-ఒక సంఖ్య ఉన్న విలువలు with .
ఇప్పుడు పరిధిని కనుగొనడానికి, ప్రమేయం యొక్క పరిమితిని తీసుకోండి.
\(\lim_{x \to\infty } \rm \frac{x}{x} = \lim_{x \to\infty }1 = 1\)
Now,
\(\lim_{x \to\infty }\rm \frac{-x}{x} = \lim_{x \to\infty }-1 = -1\).
ప్రమేయ పరిధి \(\rm f(x)=\dfrac{|x|}{x}, \ x \neq 0 \ \) is (1, -1)
