Question

Which kind of function best models the data in the table? Use differences or ratios.

X = 0, y = 1.7
x = 1, y = 6.8
x = 2, y = 27.2
x = 3, y = 108.8
x = 4, y = 435.2

Can you please help me with this? I do not understand this unit as well as the other ones.

Answer 1

I forgot to put the answers:
A) linear
B) quadratic
C) exponential
D) none of the above

Answer 2

So what did you test for ?
Did you notice that the x values increase by 1 unit
Is the difference between consecutive y values a constant? <---- if so, arithmetic or linear
is the common ratio between consecutive y values a constant? <----- if so, geometric or exponentioal
are the second difference between y values constant? <---- if so, then quadratic
