Every saturday, justin gets an allowance of $10 from his parents. during every week since justin began getting an allowance, he spends $8 and saves the remaining $2 of his allowance before he receives his next allowance. the sequence shown represents the amount of money justin has right before and right after he gets his allowance for six consecutive weeks, starting with $0.
0, 10, 2, 12, 4, 14, 6, 16, 8, 18, 10, 20
explain why this sequence is or is not a function?

a.
this sequence is not a function because the amount $10 appears in the sequence more than once.

b.
this sequence is not a function because the sequence does not form a line.

c.
this sequence is a function because each input (odd terms in sequence) maps to one output (even terms in sequence).

d.
this sequence is a function because each output (even terms in sequence) maps to one input (odd terms in sequence).

The sequence is a  function since,

Step-by-step explanation:

This sequence is a function whose domain is the set of positive integers.

The function is given by,

f(x) = 10 + (x -2)            when x is even

      = (x- 1)                     when x is odd

The sequence is a  function since,

step-by-step explanation:

i think something is missing in your question because y-1=(x-12) would not pass through the point (-4,-3). because if you replace x by -4 your are supposed to find y=-3 which is not the case her. if you replace x by -4 you find =-15.

i assume the right equation is y-1=1/4*(x-12) because this one is passing through both your points (if you are interested to know how i found that out i can tell you).

in this equation if i replace x by -4 i find y=-3 and if i replace x by 12, i find y=1 so the line representing this equation is passing through those 2 points.

then the standard form of the equation is finding an expression of y in function of x

y-1=1/4*(x-12)

y=x/4-3+1

y=x/4-2

hope that .

do you confirm there was a mistake in the question?
