Find the Equation for this Graph ?

Question

http://s82.photobucket.com/albums/j253/g_moneydakilla31/?action=view&cur

The zeros are x=3, x=-2 x=-3

The test point is -1, -2

Please help me find the equation of this graph

thanks

Answer 1

your graph and your zeros , they don`t match together

I see in your graph 4 zeros

-3, 2,2,5

dobbel zero by 2

then

f(x) = a(x+3)(x-2)(x-2)(x-5)

and prove with point(-1,-2)

-2 = a*2*-3*-3*-6

a= 1/54

f(x) = 1/54 (x+3)(x-2)(x-2)(x-5)
