Graph ofy = logbx b >1 2 1 1/b b 1 b2 If x= ------ , then y= ------ 1/b -1 1 0 b 1 b2 2 -1
Sketch the graph ofy = logb|x| b >1 y = logbx if x > 0 y = log b(-x) if x < 0 2 1 b -b -1 1 b2 -b2 If x = ------ , then y = ------ -1 0 -b 1 -b2 2 If x = ------ , then y = ------ 1 0 b 1 b2 2 Graph ofy = logb|x| b > 1 is symmetric with respect to y-axis, that is, logb|x| is an even function.
Graph ofy = logbx b < 1 If x= ------ , then y= ------ b 1 1 0 1/b -1 1/b2 -2 1 1/b2 1 1/b b -1 -2
Sketch the graph ofy = logb|x| b < 1 y = logbx if x > 0 y = log b(-x) if x < 0 If x= ------ , then y= ------ -1 0 -1/b -1 -1/b2 -2 If x= ------ , then y = ------ 1 0 1/b -1 1/b2 -2 1 -1/b2 1/b2 1/b -1 -1/b -1 -2 Graph ofy = logb|x| b < 1 is symmetric with respect to y-axis, that is, logb|x| is an even function.
