b > 0, value of the function for x going towards +∞. If
b < 0, value of the function for x going towards -∞.
m- Abscissa of maximum growth.
b- Growth rate.
q- Parameter that affects the position of the curve along the ordinate axis.
b > 0, value of the function for x going towards -∞. If
b < 0, value of the function for x going towards +∞.
n- Parameter that affects near which asymptote the maximum growth occurs.
n <= 0.
