Describe the y-intercept and end behavior of the following graph

In mathematics, a polynomial is an expression consisting of variables and coefficients which only employs the operations of addition, subtraction, multiplication, and non-negative integer exponents. An example of a polynomial of a single variable x is x² - 4x + 7. An example in three variables is x³ + 2xyz² - yz + 1.
