What is the increase in the worlds population over the last 10 years?

the one that has a slope of 1/2 and is positive.

step-by-step explanation: 2 buckets 1 trip ; 4 buckets 2 trips and so on.

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1

see the picture for the graph.

i think the answer is b.

step-by-step explanation:

not 100% sure though.

the first one is x^2+2x+2

the second one is x^2+4

the last one is x^2-4x+8
