WebJan 17, 2024 · Because exponential and logarithmic functions are inverses of one another, if we have the graph of the exponential function, we can find the corresponding log function simply by reflecting the graph over the line y=x, or by flipping the x- and y-values in all coordinate points. Let’s use some graphs WebCharacteristics of Graphs of Logarithmic Functions. Before working with graphs, we will take a look at the domain (the set of input values) for which the logarithmic function is defined. Recall that the exponential …

How to find the equation of a logarithm function from its graph?

WebSolving for a and b, we find a = y 1 − y 2 ln ( x 1 / x 2), b = exp ( y 2 ln ( x 1) − y 1 ln ( x 2) y 1 − y 2). You can check that with these value for a and b, indeed y = a ln ( b x) passes through your two points ( 1, 150) and ( 99, 300).
