Answer 1

Answer:

The correct answer is the 4th graph. (1,3 - 2,6 - 3,12 - 4, 24 - 5, 48)

just took the test.

Step-by-step explanation:

Answer 2

$f(x)=3(2)^{x-1}\\\\f(1)=3(2)^{1-1}=3(2)^0=3(1)=3\to(1,\ 3)\\\\f(2)=3(2)^{2-1}=3(2)^1=3(2)=6\to(2,\ 6)\\\\f(3)=3(2)^{3-1}=3(2)^2=3(4)=12\to(3,\ 12)\\\\f(4)=3(2)^{4-1}=3(2)^3=3(8)=24\to(4,\ 24)\\\\f(5)=3(2)^{5-1}=3(2)^4=3(16)=48\to(5,\ 48)$
