8. What is the 10th term of the geometric sequence a(n)= -3(2)^x-1

a. -54
b. -3,072
c. -10,077,696
d. -1,536

n=10

a10= - 3 (2)^(10-1)= -3(2)^9

= -1536

a function could be identified in 3 ways either on a chart,graph, or ordered pairs. first a function is that each point has its own. the rule is that there can be many x's to one y but there can not be 2 x's at different y's. so on a graph when you put a straight line through the y's there should be one dot only to be a function.
