Answer:
Step-by-step explanation:
Table for function 1,
x y Difference 1 Difference 2
2 10 - -
3 1 1 - 10 = -9 -
4 10 10 - 1 = 9 9 - (-9) = 18
5 37 37 - 10 = 27 27 - 9 = 18
6 82 82 - 37 = 45 45 - 27 = 18
Since, difference 2 is common as 18,
Table will represent a quadratic function.
Table for function 2,
x y Difference 1 Difference 2
5 16 - -
6 19 19 - 16 = 3 -
7 28 28 - 19 = 9 9 - 3 = 6
8 43 43 - 28 = 15 15 - 9 = 6
9 64 64 - 43 = 21 21 - 15 = 6
Since, difference 2 is common as 6,
Table will represent a quadratic function.
Table for function 3,
x y Ratio
1 112 -
2 56 56 ÷ 112 = [tex]\frac{1}{2}[/tex]
3 28 28 ÷ 56 = [tex]\frac{1}{2}[/tex]
4 14 14 ÷ 28 = [tex]\frac{1}{2}[/tex]
5 7 7 ÷ 14 = [tex]\frac{1}{2}[/tex]
Since, ratio is common as [tex]\frac{1}{2}[/tex].
Table will represent an exponential function.
