Answer:
a= 1
b= -1
c=0
equation looks like x²-x
Step-by-step explanation:
we have
ax²+bx+c
we know that when x=1 y=0 so plugging in 1 for x means
(doing this for the other points we get)...
a+b+c=0
c=0
a-b+c=2
Because we know c=0 we can write
a+b=0
a-b=2
Adding the two equations
2a=2
a=1
Knowing that a=1 we can easily solve for b
a+b=0
1+b=0
b= -1
