The graph of y=log base 2 of x looks like a curve that increases at an ever-decreasing rate as x gets larger. It becomes very negative as x approaches 0 from the right. The graph of y=-log …

So let's try to graph y is equal to log base two of negative x. In other videos we've talked about what transformation would go on there, but we can intuit through it as well.

You cannot have a negative base in a logarithm, and here is why: Keep in mind that the log (x), with any base, the output will be a real number no matter what as long as the input is >=0.

This topic covers: - Radicals & rational exponents - Graphs & end behavior of exponential functions - Manipulating exponential expressions using exponent properties - Exponential …

The graph of y = log 2 x is shown below. Which of the following is the graph of y = 3 log 2 (x 4) ?

When you put the negative in front of the function, that means that you are reflecting it across the x-axis.

Sal explains what logarithms are and gives a few examples of finding logarithms. Created by Sal Khan.

I learnt at school that the base of a logarithm must be positive and not equal to 1. The latter part of the rule is quite intuitive (raise 1 to any power and you'll get 1, so there is no need for such a …

Logarithms are the inverses of exponents. They allow us to solve challenging exponential equations, and they are a good excuse to dive deeper into the relationship between a function …

But the way that we've written it over here, it's actually given the dependent variable, it's easy to figure out what the independent variable needs to be for this logarithmic function.
