•
graph crosses the xaxis at (1, 0)
• when b > 1, the graph
increases
• when 0 < b < 1, the
graph decreases
• the domain is all positive real numbers
(never zero)
• the range is all
real numbers
• graph passes the
vertical line test  it is a function
• graph passes the
horizontal line test  its inverse is also a
function. • graph is asymptotic
to the yaxis  gets very, very close to the
yaxis
but does not touch it or cross it.
