Answer 1

Graph D i'm pretty sure.

Explanation:

Edge.

Answer 2

Graph (1)

Explanation:

This question is incomplete: find the figures for this question in the attachments.

Given function is,

f(x) =
`3(2)^((x-1))`

f(1) =
`3(2)^(1-1)` = 3

f(2) =
`3(2)^(2-1)=6`

f(3) =
`3(2)^(3-1)` = 12

f(4) =
`3(2)^(4-1)` = 24

f(5) =
`3(2)^(5-1)` = 48

Table for the points on the graph is,

x 1 2 3 4 5

f(x) 3 6 12 24 48

If we plot these points given in the table, we get the graph which matches to the graph given in option (1).

Therefore, Graph (1) will be the answer.
