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 - 4
D. y= x^2 + 5
Is it A or C?
16) y = x^2 + 5 (D)
The questions might change if you're looking at this years later, so just make sure there's an answer the exact same as mine.
Also just did it so I can see that it's right
For 2017 people, the answers may be different, but B is the answer for #16.
2021 answer is D as well I think
Welp Im gonna try b but I'm not sure.......
Still D??
Still D
I would try subbing in the points
e.g. (0,5) works in A,B, and D only
(1,4) works in B
try if the others work in B
well ???
