These graphs have asymptotes and never intersect the y-axis and have 1 intersection with the x-axis. Log graphs are functions. For every value of x, there is only one value of y. Log graphs are reflections of exponential graphs along the line y = x, and they are NOT exponential. No turning point. The line of symmetry is always diagonal to the axises.
a ≠ 0. If a > 0, curve will go upwards. If a < 0, curve will go downwards.
