Math Problem Statement

Which table shows y as a function of x?

Solution

The question is asking which of the given tables shows yy as a function of xx. In mathematics, for yy to be a function of xx, each value of xx must correspond to exactly one value of yy. In other words, no xx-value should be paired with more than one yy-value.

Let's analyze each table:

Table F:

  • x=13x = -13, y=2,0,5,7y = -2, 0, 5, 7
  • The same xx-value of 13-13 corresponds to multiple yy-values (−2, 0, 5, 7), so this is not a function.

Table G:

  • x=6x = -6, y=3y = 3
  • x=1x = -1, y=1,5y = -1, 5
  • x=10x = 10, y=9y = -9
  • The same xx-value of 1-1 corresponds to two different yy-values (−1, 5), so this is not a function.

Table H:

  • x=1x = 1, y=4y = 4
  • x=3x = 3, y=4y = 4
  • x=7x = 7, y=4y = 4
  • x=12x = 12, y=4y = 4
  • Each xx-value corresponds to exactly one yy-value (in this case, all are 44), so this is a function.

Table J:

  • x=9x = -9, y=7y = -7
  • x=2x = -2, y=5y = -5
  • x=0x = 0, y=0,6y = 0, 6
  • The xx-value of 00 corresponds to two different yy-values (0, 6), so this is not a function.

Conclusion:

The correct table that shows yy as a function of xx is Table H.

Tip: Remember, in functions, each input (value of xx) must map to exactly one output (value of yy).
