Answer:
<u>x=0</u>
all you have to do it plug the diffrent answers into as x and see which one works out, in this case 0 works on both side to get it equale

Answer: Graph D will be correct graph for the given function.
Explanation:
Given function 
Since it is a bi-quadratic equation thus it must have 4 roots and (0,1) is one of its point.
Moreover, the degree of the function is even thus the end behavior of the function is
, as
and
as 
In graph A, function has four root but it does not have the end behavior same as function f(x).( because in this graph
, as
and
, as
.) so, it can not be the graph of given function.
In graph B, neither it has four root nor it has the end behavior same as function f(x).(because in this graph
as
and
as
.) so, it can not be the graph of given function.
In graph C, neither it has four root nor it has the same end behavior as function f(x).(because in this graph
as
and
as
.) so, it also can not be the graph of given function.
In graph D it has four root as well as it has the same end behavior as the given function. Also it passes through the point (0,1).
Thus, graph D is the graph of given function.

Hence, The value of a, b, c, d and e is 23, 31 ,60 ,33 and 51 .
