Answer:
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 :
f(x) = x(x+1)(x-6)
