When the 1st differences are equal, it is a ______ function.

• linear

• quadratic

• exponential

• cubic

What are the 1st differences?

• +8, so it is linear

• -8, so it is linear

• +2, so it is linear

• +8, so it is quadratic

Zach was making a table of 1st and 2nd differences for a quadratic function. Where is his mistake?

• What are you talking about? There's no mistake!

• He messed up on the first-first difference (red one). It should be a positive 2.

• He messed up on the second-first difference (blue one). It should be a positive 2.

• He messed up on the third-first difference (green one). It should also be -2.

y=3x²

• a=3 and it is quadratic

• a=-2 and it is quadratic

• a=3 and it is exponential

• a=3 and it is linear

(x,y)

(0,5)

(1,0)

(2,-5)

(3,-10)

These values have a constant _____________ difference of _________.

• 1st; +5

• 1st; -5

• 2nd; +5

• 2nd; -5
