Consider the given function,


f(x)=-(x-4)(x+1)

This is a quadratic function in factor form.

Consider that the function is zero when alteast one of the factors becomes zero,


\begin{gathered} y=0 \\ -(x-4)*(x+1)=0 \\ x-4=0\text{ or }x+1=0 \\ x=4\text{ or }x=-1 \end{gathered}

Thus, the zeroes of the quadratic function are 4 and -1.

It means that the function passes through the points (-1,0) and (4,0).

Consider that the vertex of a parabolic function is given by,


undefined
