Domain of a Function

After we complete 3-60 in Algebra, analyze the picture found at the link below. Describe in your own words what that picture tells you. AND Why would I include this picture as a resource during this unit? PLEASE REPLY!

  1. To show us that the f is the function for what you do to x to turn it into y.

  2. The picture helps because you have a function with the x and then it equals the y. Also it represents what we are doing like a table.

  3. Because whatever you do to "x", always becomes part of the "y". The "function" turns "x" into "y".

  4. You can use any set oF number to get the whole set of numbers

  5. The function is how you get to the X to the Y. The picture helps because it is showing the function on how to get X to the Y.

  6. 2x can F it would be the range

  7. The little x combines with the f to create a big y and the colors represent that you can use different numbers to x but you will always get a y to go with it. Also thhat x can turn into y.

  8. The picture is basically showing that the function helps you get the answer for the X and the Y. The X can fit into the Y.

  9. The picture tells me that what ever you do to x becomes a part of the y as long as you apply the rule to x.

  10. The picture is showing me that you can use any numbers to get a new set of numbers using a rule. You are using this because it is using the x to y formula.

  11. That the smaller oval in the y part is the range for the f part. That a x fits into the f part would be the range so you could take any number and turn it into x and you still have to apply the rule to get it.

  12. This picture shows x in y and the arrows show that when you apply the number of x to the equation you get y.

  13. F is known as the range. And when you have an x and an x and they fit in the f and x can be any number

  14. This picture tells us that we can turn x into a y. This picture means that you can plug a number (x) into a rule to get a y.

  15. The picture represents the function and the x which equals the y.

  16. It turns x into y by a rule,and all you need to do the rule correctly

  17. The reason why this picture is there is it shows that yup can have any x and if you follow the rule you will get y.

    ReplyDelete
  18. That X turns into Y and you need a rule after X to get a why. It does not matter what set of numbers you have as long as you follow the rule.

  19. You can put by number in for so as long as you put in some numbers to x you can get the outcome you need for y.

  20. 11/1/10
    The range of f changes the shadow of y

  21. The pic shows u need to plug in x to get y
    For the input

    ReplyDelete
  22. You always need to do something to x to equal y.

    ReplyDelete
  23. The picture tells us to plug in x to get y
    He put this in because in this unit we go from x to y.

    ReplyDelete
  24. The picture tells us to plug in x to get y and it's in our unit because were learning about inputs.

    ReplyDelete
  25. I think it means that you have to do manipulate x somehow to get y.

    ReplyDelete
  26. You need a formula or something to do to x to get the value of y.

    ReplyDelete
  27. X gos into y through a formula, or f.

  28. You can put any number for x. The x circle fits in the yellow. Y is bigger than x. This tells us that x is only one part of y. Meaning that y is the whole. He gave this to us because y is the whole in our equations and x is just one side of y.

  29. The image shows x compared to y. F is what is left to y when take x away from it

    ReplyDelete
  30. I think the picture tells us that X somehow will make a Y. I think you put that picture in this unit because it is kind of like a graph.

    ReplyDelete
  31. The picture shows You need to change x to make y

    ReplyDelete
  32. It shows you how to go from x to y.

    ReplyDelete
  33. To get y you need to have an x! Hannah sheedy

  34. It helps because you must something x to get y.So by putting x in it your getting your equation. So you must take your x and your equation too get your y. Y is our whole.

  35. The very detailed picture shows us how to get y from x using very difficult and in depth equations. You put this on here to help us.

    ReplyDelete
  36. The picture is showing that x can always go into y because it is part of the equation that makes y.
