If you mean these: Domain: [0;inf] Range: [-inf;inf] Equals: log(x^9) Inverse: 10^(x/9) Derivative: 9/(x ln10) X-intercept: [1;0] Y-intercept: NONE! Vertical Asymptote: x=0 Increases It's a not symmetric logarithm function. x=1 is its only root Hope could help and if you didn't mean these then sorry! :)
