Answer:
it can help you with answer a math problem
Step-by-step explanation:
Ok... so this question can be solved by using simultaneous equations.
Use the general from of a parabola
you know the value of c, the y-intercept... y = -4
which means the equation is
now use the other 2 points to get 2 equations in 2 unknowns
(-2, -20) just substitute
this becomes
now the other equation using (4, -20)
The simplified form is
Answer:
3, 4 , 5 , 6 is your answer.
I HOPE IT WILL HELP YOU.
Thank you.

If the roots of the equation f(x)=0 are -4,-1, 2 and 5, then binomials (x+4), (x+1), (x-2) and (x-5) are factors of needed polynomial.
Thus, the polynomial will have form
where a is real coefficient (positive or negative). This polynomial has degree 4 as needed.
The form of the graph depends on the sign of coefficient a. Attached diagrams show two different cases of possible forms of graphs (first one for positive coefficient a, second one for negative coefficient a).
