to graph the function g(x) given below. Graph and give the equation of the asymptote. Use the graph to determine the domain and range of g(x).

Evaluate the following expression without using a calculator.

Evaluate the expression without using a calculator.

Use properties of logarithms to condense the logarithmic expression. Write the expression as a single logarithm whose coefficient is 1. Evaluate logarithmic expressions if possible.

The loudness level of a sound can be expressed by comparing the sound’s intensity to the intensity of a sound barely audible to the human ear. The formula describes the loudness level of a sound, D, in decibels, where I is the intensity of the sound, in watts per meter squared,and I 0is the intensity of a sound barely audible to the human ear. Use this information to answer parts (a) and (b) below.

Solve the following exponential equation by expressing each side as a power of the same base and then equating exponents.

Complete the table shown to the right for the population growth model for a certain country.
