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).

we can factor this degree into three parts and then it's easy for us to see the other. There are stories solutions which are zero miners to m two and this is a graph off the above function depicted by the programming language python. When X is smaller than miners to the first part is positive. The 2nd and 3rd parts lega tive enhance the production off these three parts is positive, which is consistent with a graph here when X is between minus two and zero. The sign off these three pairs positive, positive and negative Enhance the production off the negative, which are also consistent with a group here. But access between there and to the sign off these three parts, uh, negative, positive and negative enhance. The production is positive, just as a graph depicted here X is greater than two. The sign of these very parts a negative, positive and positive enhance their production is negative, which is can also consistent with a graph here
