# Maths: Polynomial Graphs and Values?

Let f be a quartic polynomial (ie. a polynomial of degree 4). Suppose that f has zeros at -2; 1; 3; 4 and that f (0) = 4.

- Sketch a graph of f.

- If f(x) is written in the form:

f (x) = A(x - a)(x - b)(x - c)(x - d)

then find the values of A; a; b; c; d.

- Sketch a graph of f.

- If f(x) is written in the form:

f (x) = A(x - a)(x - b)(x - c)(x - d)

then find the values of A; a; b; c; d.
