and what are u willing to find out? :P

@andy11  just plug given values of x in the equation and then match your answer

mayankdevnani · Answer

let's take an example :-
x=-1 and f(x)=3
your equation:-
$$\huge \bf f(x)= x^4-2x^3$$
plug x=-1,
$$\huge \bf f(x)=1-2(-1)=1+2=3$$

So,it satisfies.

similarly,can you do yourself?  @andy11

anonymous · Answer

ok yeah i kinda get it. so for the next one i would try i would replace the -1 with 0?

mayankdevnani · Answer

correct

mayankdevnani · Answer

now,you get it

anonymous · Answer

mayankdevnani · Answer

welcome :)

anonymous · Answer

ok so i got 1 for the answer. is that correct or did i do somthing wrong

anonymous · Answer

A plot from Mathematica is attached.

acxbox22 · Answer

all of the x values satisfy the equation
so if you plug all the x values in the table into the equation, you get f(x)
