A parabola can cross the x -axis once twice or never. The degree of a polynomial is the highest power of the variable x. You can specify typename or like but not both.
The zeros of a function are the x coordinates of the x intercepts of the graph of f.
A pole of f is a zero of 1f. For instance the equation y 3x 13 5x 3 has two terms 3x 13 and 5x 3 and the degree of the polynomial is 13 as thats the highest degree of any term in the equation. A root of a polynomial is a zero of the. This is a function and if we use function notation we can write it as follows f x x if x 0 x if x.
