Step 1

From the graph, the zeroes of the quadratic function are;

$\begin{gathered} x=-1 \\ x=4 \end{gathered}$

Step 2

Find the formula for the quadratic function in the graph.

$\begin{gathered} x+1=0 \\ x-4=0 \\ (x+1)(x-4) \\ x^2-4x+x-4 \\ x^2-3x-4 \end{gathered}$

Hence the formula for the quadratic function graphed is
