A quartic function has a equation y=ax^4 + bx^3 + cx^2 + dx + e. Its graph cuts the x-axis at (-1,0) and (2,0). One of these intercepts is a stationary point if inflection. If the graph passes through (1,16), find a, b ,c, d and e.
First i started using y=k(x+a)(x+b)(x+c)(x+d)
then i sub in the x values in the equation
y=k(x-1)(x+2)(X-1)(x+2)
after i sub in (1,16)
is this how i suppose to do it? or it is wrong?
