How do you write absolute value equations graphing

However, if we put a logarithm there we also must put a logarithm in front of the right side. This is commonly referred to as taking the logarithm of both sides. This is easier than it looks.

How do you write absolute value equations graphing

But what we're now going to explore is functions that are defined piece by piece over different intervals and functions like this you'll sometimes view them as a piecewise, or these types of function definitions they might be called a piecewise function definition.

Let's take a look at this graph right over here.

This graph, you can see that the function is constant over this interval, 4x. And then it jumps up in this interval for x, and then it jumps back down for this interval for x. Let's think about how we would write this using our function notation.

Then, let's see, our function f x is going to be equal to, there's three different intervals. So let me give myself some space for the three different intervals.

Now this first interval is from, not including -9, and I have this open circle here. Not a closed in circle. So not including -9 but x being greater than -9 and all the way up to and including I could write that as -9 is less than x, less than or equal to That's this interval, and what is the value of the function over this interval?

Well we see, the value of the function is It's a constant -9 over that interval. It's a little confusing because the value of the function is actually also the value of the lower bound on this interval right over here. It's very important to look at this says, -9 is less than x, not less than or equal.

If it was less than or equal, then the function would have been defined at x equals -9, but it's not. We have an open circle right over there. But now let's look at the next interval. The next interval is from -5 is less than x, which is less than or equal to Over that interval, the function is equal to, the function is a constant 6.

It jumps up here.

Sometimes people call this a step function, it steps up. It looks like stairs to some degree. Now it's very important here, that at x equals -5, for it to be defined only one place. Here it's defined by this part. It's only defined over here.Standard Form Algebra Standard Form of a linear equation: 2x y 6 3x 7y 21 2x 6y 1 Examples above are Linear Equations written in Standard Form.
