Question

Which is the graph of a logarithmic function?
On a coordinate plane, a hyperbola is shown.
On a coordinate plane, a straight line is shown.
On a coordinate plane, a parabola is shown.
On a coordinate plane, a curve starts in quadrant 4 and curves up into quadrant 1.

Answer 1

The last one: "a curve starts in quadrant IV and curves up into quadrant I."

Reason: y = log_b(x) (b>1) is defined only for x>0, has a vertical asymptote at x=0, passes through (1,0), and rises from −∞ near x→0+ up through quadrant IV into quadrant I as x increases.
