Asked by b e a n

which quadratic rule represents the data in the table?
x: -1,0,1,2,3
y: 4,5,4,1,-4

a. y=2x^2+5
b. y=-x^2+5
c. y=x^2-5
d. y=x^2+5

I really need help with this one its for a test! (Sorry if I seem demanding or rude)

well, C is out, since y(0) = +5
Now plug in other values to see what works.

Thank you so much! I am sorry for asking but can you explain how to plug in the values. You don't have to use the problem as an example, tbh I don't know how to plug in the numbers correctly. I tried to make assumptions on how to do it with what you did with c. but I am completely clueless.
