Which of the following represents a function? A.{(-2, 1), (-2, 0), (-2, 1), (-2, 2)}
B.{(-1, 0), (0, 1), (1, 2), (2, 3)}
C.{(1, 3), (3, 1), (2, 3), (3, 2)}
D.{(5, 5), (5, 4), (5, 3), (5, 2)}

70,000 + 6,000 + 800 + 30

step-by-step explanation:

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.

a = 3.14

b = 18

c = 18/5 or 3.6 or 3 3/5
