We were asked to determine whether the equation defines y as a function of x.

Could you explain this problem? y = x^2

  • Algebra -

    if each x maps to a single y, then y is a function of x.

    So, is there any value of x which produces more than one value of y?

    Another useful way to decide is to graph the relation. If no vertical line intersects the graph in more than one place, then it is a function.
