Question

Melinda has shown that a function, f(x), increases by 4 for every unit in the domain. What does this prove?

The function f(x) is an arithmetic sequence.
The function f(x) is a geometric sequence.
The function f(x) is not a sequence.
This does not prove anything.

Answer 1

note: the increase is the same flat amount each time, is that arithmetic or geometric or neither?

Answer 2

im not sure :/

Answer 3

Answer 4

looking at this, do you have any new ideas about what it might be?

notice that arithmetic = adding or subtracting the same thing each time; geometric = multiplying/dividing by the same thing each time

Answer 5

geometric?

Answer 6

"increases by 4 for every unit" that means we are adding 4 each time, so arithmetic not geometric (A)

Answer 7

ohhhh because its adding 4 not multiplying by 4 i get it thanks so much!
