Algebra (Last Question)

posted by .

I have
- to graph each relation
- decide if it is a function
- state the domain and the range.

1) {(2,3),(4,-3),(5,1),(-1,3)}

how would I decide if something is a function in general?

I kind of remember the domain and the range,but since I did this 2 years ago I forgot. Is the domain the x and the range the y?

  • Algebra (Last Question) -

    I found out about domain and range

    how would I solve this then:

    y=line x-3 line

    y^2 = x

    y = (x+1)/(x-3)

  • Algebra (Last Question) -

    for those how would I get the domain and range

  • Algebra (Last Question) -

    for y = sqrt x

    the domain is like R something?

  • Algebra (Last Question) -

    You need to look up your notes and your textbooks to review the chapter(s) on functions, domain and range.


    The graph is an arrow graph that relates each member of the domain to the corresponding member in the range.
    The domain contains the x-value of all the ordered pairs, and the range, the y-values.
