A Polynomial function f is a function of the form:
where a0, a1, ..., an
are real numbers.
Domain: All polynomials have the same domain which consists of all real numbers, because there are no denominators (so no division-by-zero problems) and no radicals (so no square-root-of-a-negative problems). There are no problems with a polynomial. There are no values that I can't plug in for x.
Range: The range will vary from polynomial to polynomial. I would be a good idea to draw the function to get the range.
Find the domain and range of y = x+4
Let's see the graph of this function:
