Further examples of identifying a non-linear rule for a given table of values

Question 4

x	0	1	2	3
y	4	3	0	−5

Which equation possibly describes the relationship between y and x?

Question 4 - multiple choice question

y = x + 4		y = 4 − x		y = 4 − x²		y = 4 + x²

Question 5

x	0	1	2	3
y	3	1	−5	−15

Which equation possibly describes the relationship between y and x?

Question 5 - multiple choice question

y = −2x + 3		y = 3 − x		y = 3 − 2x²		y = 3 + 2x²
