Answer:
Step-by-step explanation:
plot five points of f(x)=(1/2)^x
f(0)=(1/2)^0=1
f(1)=(1/2)^1=1/2... through five gives you
y=1, 1/2, 1/4, 1/8, 1/16 for points
(0, 1),(1, 0.5),(2, 0.25),(3, 0.125),(4, 0.0625)
Markus has 6 marbles in each bag.
Markus has 18 marbles and 3 bags
If you divide 18 marbles by 3 bags that would be 6 marbles in each bag.
Your question is not very clear, hope I get what you want
2x-1+3
=2x+2
=2(x+1)
