Final Answers
a) False. Nothing in the definition of a geometric sequence requires the common ratio to be always positive. For example,
b) False. Linear systems only have a solution if the lines intersect. So y = x and y = x + 1 will never intersect because they are parallel.
c) False. does not have an inverse.
d) True. has multiple solutions.
e) True.
f) False.
