From this analysis, it can be concluded that as the base of a logarithmic function increases, the graph approaches the asymptote of x = 0 quicker. Also, the function may increase at a slower rate as the base increases.

Rewrite the equation by factoring out a - 1 from the exponent to read . From the equation, you can see that the horizontal shift will be to the left 10 units and there will be a reflection over the y-axis. Therefore, reflect the graph of over the y-axis and then shift (move) the reflected graph left 10 units.

In mathematics, the logarithm is the inverse function to exponentiation. That means the logarithm of a given number x is the exponent to which another fixed number, the base b, must be raised, to produce that number x.

STEP 1: Replace the function notation f\\left( x \\right) by y. STEP 2: Switch the roles of x and y. STEP 3: Isolate the log expression on one side (left or right) of the equation. STEP 4: Convert or transform the log equation into its equivalent exponential equation.

To tell Excel to use logarithmic scaling of the value (Y) axis, simply select the Logarithmic Scale check box and then click OK. Excel re-scales the value axis of your chart to use logarithmic scaling.

Select the "Scale" tab on the Format Axis window. Click the "Logarithmic Scale" check box near the bottom of the window. This changes the chart's axis to a log scale.

How To: Given a logarithmic function Of the form f(x)=logb(x+c) f ( x ) = l o g b ( x + c ) , graph the Horizontal Shift. Identify the horizontal shift: If c > 0, shift the graph of f(x)=logb(x) f ( x ) = l o g b ( x ) left c units. If c < 0, shift the graph of f(x)=logb(x) f ( x ) = l o g b ( x ) right c units.
