Correct Answer
A. (2)
Concept
This expression is the sum of distances from (1) and (-1), whose minimum is (2). In distance-type modulus graphs, use the gap between fixed points.
Why this answer is correct
The correct answer is A. (2). This expression is the sum of distances from (1) and (-1), whose minimum is (2). In distance-type modulus graphs, use the gap between fixed points.
Exam Tip
यह अभिव्यक्ति (x) की (1) और (-1) से दूरियों का योग है, जिसका न्यूनतम (2) है। दूरी वाले मापांक में बिंदुओं के बीच का अंतर उपयोगी होता है।
