Answer:
$16,700
Step-by-step explanation:
Subtract: 38428
<u>-21728</u>
16700
You will need to add 10 to the hundred's place by subtracting 1 from the thousandth's place: 37,4(+10)28. Then you subtract as usual.
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).
Do what is in the parentheses then add
I think the most appropriate answer would be "-6.58".
I hope it helped you!
