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.
