Write the cubic function.

Step-by-step explanation:

hello :

let f this function

the roots of this function are : -1 , 0 ,6   so ;    f(x) = ax(x+1)(x-6)

now calculate : a  but this graph passes by : (1, -10)  means f(1) = -10

put : x=1   and  f(x) = -10

-10 = a(1)(1+1)(1-6)

-10a = -10    so : a= 1

conclusion :
