Name the Functions - College Algebra

  • 0:00 - 0:03
    Now you may not have heard the term constant function before,
  • 0:03 - 0:09
    but intuitively we think that this is a function that has a constant value, at all values of the input.
  • 0:09 - 0:16
    That's what graph A is.
    It's of the form y equals some constant, c, let's say.
  • 0:16 - 0:20
    Actually in this case it looks more like 3,
    so we'll just write that.
  • 0:20 - 0:23
    Linear functions you recognize.
    It's graph C right here.
  • 0:23 - 0:26
    The quadratic function is the parabola, graph F.
  • 0:26 - 0:33
    The absolute value function, which you saw in a problem set earlier in the course, is graph B.
  • 0:33 - 0:36
    The cubic function is graph D.
  • 0:36 - 0:42
    And the square root function is graph E.
    Now you may not have seen this graph before either.
  • 0:42 - 0:46
    But as always, you can test points picking values of x
  • 0:46 - 0:49
    and then plugging them into the function to figure what the y coordinate should be.
  • 0:49 - 0:54
    The graph of this function is
    y equals the square root of x.
  • 0:54 - 0:58
    So if x equals 0, y equals 0.
    If x equals 1, y equals 1.
  • 0:58 - 1:06
    And we can see that moving further over,
    if x equals 5, y equals just over 2.
