If x is a real numbers and |x|<5,then
x≥5
−5<x<5
x≤−5
−5≤x≤5
Given,|x|<5⇒ −5<x<5 [∵ |x|<a⇒ −a<x<a]
If - x≤ - 5, then which of the following is the incorrect solution?
Find x and y if [5x3y]=[−25−15]
Examine the following functions for continuity :
(a) f(x) = x - 5
(b) f(x)=1x−5,x≠5
(c) f(x)=x2−25x+5,x≠−5
(d) f(x)=|x−5|.
