How does ƒ(x) = log x (2) compare with g(x) = log 2(x)? Here is one way to find out. a. Use the equation log ab = (ln b)/(ln a) to express ƒ(x) and g(x) in terms of natural logarithms. b. Graph ƒ and g together. Comment on the behavior of ƒ in relation to the signs and values of g.

Rate of Change
The relation between two quantities which displays how much greater one quantity is than another is called ratio.
Slope
The change in the vertical distances is known as the rise and the change in the horizontal distances is known as the run. So, the rise divided by run is nothing but a slope value. It is calculated with simple algebraic equations as:
