Answer:
1. EXPONENTIAL
2. LINEAR
3. NEITHER
4. LINEAR
Explanation:
To classify if the as linear, exponential, and neither, we need to test each of them to see what pattern they have.
For f(x) = 3, 9, 27
and x = 0, 1, 2
This can be represented by:
[tex]f(x)=3^{x+1}[/tex]
This is EXPONENTIAL
For f(x) = 9, 12, 15
and x = 0, 1 , 2
This can be written as:
[tex]f(x)=3x_{_{}}+9[/tex]
This is LINEAR
For f(x) = -8, 16, 4
and x = 0, 2, 4
This doesn't have a patter, so it is NEITHER
For f(x) = 16, 32, 48
and x = 1, 2, 3
This can be written as:
[tex]f(x)=16x[/tex]
This is LINEAR
