In mathematics, a function is a relation between a set of inputs and a set of permissible outputs with the property that each input is related to exactly one output. An example is the function that relates each real number x to its square x^2. The output of a function f corresponding to an input x is denoted by f(x).

to deter mine. The zero of this function. We can factor it like this and we can easily see that it has raised of oceans. X equals zero X equals minus two and X equals two. I also use the programming language pies on to draw the graph off this function. As you can see, the X is smaller than miners to of X is greater than two. It's positive when X is between minus two and zero. It's negative, but exits between zero and two. It's also negative. Enhance. This function has raised solutions. X equals minus two. X equals zero and X equals two.
