Answer:

y=(x+2)(x-5)

Explanation:

The roots of the function (where it touches the x axis) are (0,-2) and (0,5), so you have to pick the equation with those roots. This equation if y=(x+2)(x-5). This is because when y = 0, when you insert those roots as x values the right side also equals zero. For example:

0=(x+2)(x-5)

set x as -2

0=(-2+2)(-2-5)

0=0*-7

0=0

The same would also happen if you inserted 5, showing that this equation is the correct one for this set of roots.
