•
graph crosses the yaxis at (0,1)
• when b > 1, the graph
increases
• when 0 < b < 1, the
graph decreases
• the domain is all real
numbers
• the range is all positive
real numbers (never zero)
• 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 xaxis  gets very, very close to the xaxis
but does not touch it or cross it.
