Understanding Sequences and Graphs

What is a continuous graph?

• A graph where points are connected because it makes sense to do so

• A graph that only uses whole numbers

• A graph where points are not connected

• A graph that cannot have decimal values

Why is the graph of buying t-shirts considered discrete?

• Because the cost of t-shirts is always the same

• Because t-shirts are sold in whole numbers only

• Because t-shirts are not sold in stores

• Because you can buy half a t-shirt

In the context of graphs, what does it mean if you can have decimal x values?

• The graph is discrete

• The graph is continuous

• The graph is undefined

• The graph is linear

What is a sequence?

• A random list of numbers

• A list of numbers that are all the same

• An ordered list of numbers with a pattern

• A list of numbers with no specific order

What is the input for a sequence called?

• t

• y

• x

• n

What is the output for a sequence called?

• f(x)

• y

• t(n)

• z

How is the zeroth term in a sequence determined?

• By adding 1 to the first term

• By subtracting 1 from the first term

• By doing the opposite of the sequence's pattern

• By dividing the first term by 2

Which of the following is an example of a sequence?

• 1, 1, 2, 3, 5

• All of the above

• 2, 3, 5, 7, 11

• 2, 4, 8, 16, 32

Why can't sequences have decimal term numbers?

• Because sequences are always continuous

• Because sequences are always discrete

• Because sequences can only have negative numbers

• Because sequences are not related to functions

What must the input 'n' in sequences always be?

• A fraction

• A negative number

• A decimal number

• A whole number
