Question
15.
Do the data in the table represent a linear function? If so, write a rule for the function.
x –3 –2 –1 0 1
y 1 –2 –5 –8 –11
(1 point)
yes; y = –3x – 8
yes; y = 1/3x – 8
yes; y = 1/3x + 8
yes; y = 3x + 8
16.
Write a quadratic rule for the data in the table.
x –1 0 1 2 3
y 4 5 4 1 –4
(1 point)
y = –2x^2 + 5
y = –x^2 + 5
y = x^2 – 5
y = x^2 + 5
Can you please also explain how to solve this? Thanks
