So first things first. Is this a function or not? This is not a function. Why? Because he input zero as multiple outputs and those outputs are negative one and positive one. So not a function be. The domain is all real numbers because this graph goes infinitely from left to right. So all real members and see the range. Let&#x27;s see, it goes infinitely from the bottom of the graph. Negative infinity to positive infinity, but nothing in between. Negative one and positive one. So how about we&#x27;ll say X says that X is less or no? Why such that? Why is less than or equal to negative one? Or I is greater than or equal to output the or equal to in later, um one. So come back here and put the symbol in here.

this question. First assess. If this scrap represents a function, we can determine this by using the vertical line test. As you can see, no matter where we draw a vertical line, the Graf will only intersect this line once. So it must be true that this is a function. Now we need to define the domain of this function that&#x27;s gonna be equal to any real number. So the domain is that X is an element of all real numbers. Not to find the range of this function, as you could see from the graph, why can never be unless the negative one. So the range of this function is why it&#x27;s more than or equal to negative one.

this problem. First assets of this graph represents a function because the term this by using the vertical line rule from drawing a vertical line, we can see with the scrap intersects the vertical line in two points and therefore, this cannot be a function. Now we to find the domain of this graph. As you can see, X has to be a more than equal to negative too. So the domain of this function is access more than equal to you. Negative too. Lastly, to find the range of this graph in this case, why could be any real number? So the range is all the set of all real numbers.

Okay. First thing is we&#x27;re to determine if this is a function or not. This is a function every inputs has exactly one output doesn&#x27;t matter that all the output to the same they all every input has one output. So for be the domain, Um, that&#x27;s all real numbers. And for see the range, that is just the number two. So it&#x27;s just that set of I mean, it always comes up tubes of the ranges to or maybe why such the Why equals two. There&#x27;s something like that.

this question. First assess of this graph represents a function. We could turn this by using the vertical line test, as you could see, no matter where we draw a vertical line, The graph only intersect the line at one point, so it must be true, and no two ordered pairs have the same first owned. Or, in other words, this must be a function. Now we need to find the domain of this function. As you can see from the Graff, X cannot be more than three, and they cannot be less than negative. So the domain is all three on numbers from negative 3 to 3 on for the range. Why cannot be less than zero and copy more than four. So the range of this function is all the real memories from 0 to 4.

Cory Kuzinski · Answer

this does look like a function to me. Every input has one output. So either domain, Um, that is Oh, but it like this. We&#x27;ll say it&#x27;s x such. That X is between, what? One and 123456 So? So there&#x27;s the domain. All right. The range is gonna be on Lee. A certain set of why values so goes from zero. It looks like to about 2.5. So we&#x27;ll say between zero and 2.5.
