Completing the square give you x 2 3 2 11 9. The graph approaches x 3 or thereabouts more and more closely so x 3 is or is very close to the vertical asymptote. Since this function uses natural e as its base it is called the natural logarithm.
Fx log e x Where e is Eulers Number 2718281828459.
Here log x y is known as the logarithmic form and xz y is known as the exponential form. The graph approaches x 3 or thereabouts more and more closely so x 3 is or is very close to the vertical asymptote. Here we use the notation ln x or ln x to mean log_e x. Completing the square give you x 2 3 2 11 9.
