For questions 3-4 which kind of function best models the data in the table? use differences or ratios.

x y

0 -1
1 -0.5
2 0
3 0.5
4 1

a)liner
b)quadratic
c)exponential
d)none of these

x y

o 1.7
1 6.8
2 27.2
3 108.8
4 435.2

a)liner
b)quadratic
c)exponential
d)none of these

3 - A

4 - C

Step-by-step explanation:

Ques 3: From the table, we see that,

The slope of the points are given by,

Thus, the equation of the function is, .

So, the best function for this model is a linear function.

Hence, option A is correct.

Ques 4: From the table, we have,

The change in the y-values is,

Thus, the equation of the function is,

Hence, the best function for the model is an exponential function.

So, option C is correct.

answer: all the values are within because it has a pattern that repeats from -6 to 4.

good luck!
