It needs to be the whole term squared, as in the first logarithm. The second logarithm is as simplified as we can make it.

We will just need to be careful with these properties and make sure to use them correctly. When we say simplify we really mean to say that we want to use as many of the logarithm properties as we can.

Here is the answer for this part. You see this right over here, even with all the decimals and the negative signs, this is essentially a line.

So, when x is equal to negative two, we have negative 0. Also, we can only deal with exponents if the term as a whole is raised to the exponent. Piecewise functions Video transcript - [Voiceover] So, I have this somewhat hairy function definition here, and I want to see if we can graph it.

We will have expressions that look like the right side of the property and use the property to write it so it looks like the left side of the property. The domain of f is the set of all real numbers. This will use Property 7 in reverse.

I am going to draw my best attempt, my best attempt, at the line. We have graphed this function that has been defined in a piecewise way. This is going to be, what is this? We started x equals negative two, when x equals negative two negative two plus seven is, negative two plus seven is five.

Another example involving absolute vaule. As x becomes very large, e -x also approaches zero. Therefore, we need to have a set of parenthesis there to make sure that this is taken care of correctly. Solution to Example 7: But a closed point see above and an open point at the same location becomes a "normal" point.

In these cases it is almost always best to deal with the quotient before dealing with the product.Activity: Graphing Absolute Value Functions With a partner, complete the Graphing Absolute Value Graphing Absolute Value functions on a TIĀ Example 3: Write the equation for.

A function made up of 3 pieces. The absolute value of complex number is also a measure of its distance from zero.

However, instead of measuring this distance on the number line, a complex number's absolute value is measured on the complex number plane.
