A logarithmic function with a base has the form y=logax, where a>0 is not 1.
By the logarithmic property, the logarithmic function is reduced by x=a^y. In simple words: the logarithm of the number x on the base a is the exponent of the degree to which you want to build a to get x
The graph of a logarithmic function is a curve that is right of the coordinate axis. The graph of the function always intersects the point (1;0).
The scope and scope of the function are all valid numbers.
At a>1, the graph of the logarithmic function increases throughout the interval. At 0<a<1, the function decreases over the entire domain of the definition.
