Will mark brainliest! Please help! The first four terms of a sequence are shown below:
9,5, 1, -3
Which of the following functions best defines this sequence? (5 points)
1) f(1) = 9, f(n + 1) = f(n) - 4; for n 2 1
2) f(1) = 9, f(n + 1) = f(n) + 4; for n 2 1
3) f(1) = 9, f(n + 1) = f(n) - 5; for n 2 1
4) f(1) = 9, f(n + 1) = f(n) + 5; for n 2 1

i can you answer this question sweetie!

step-by-step explanation:

if gloria has "carry over" minutes, (that is, any minutes paid for but not used in a month can be applied to her payment for minutes in the next month,) her total usage for the three months is: total minutes = 320 + 243 + 489 = 1052 minutes number of 200 minute blocks = 1052/200 = 5 r52 (that is 5 with a remainder of 52) rounding up the number of 200 minute blocks gives her usage for the three months as 6 blocks. the cost for six blocks is 6 x $25 = $150 she also has 200 - 52 or 148 carry over minutes if gloria pays each month and unused minutes are lost, applying the rounding up procedure to each month gives: first month usage of 320 minutes rounds up to 2 blocks of 200 minutes for a payment of 2 x $25 = $50 second month usage of 243 minutes rounds up to 2 blocks of 200 minutes for a payment of 2 x $25 = $50 third month usage of 489 minutes rounds up to 3 blocks of 200 minutes for a payment of 3 x $25 = $75 total payments for the three months are $50 + $50 + $75 = $175 get the plan with carry over minutes!

step-by-step explanation:

substitution for (0,1)

y=x^2+4x+1

1=0^2+4(x)0+1

1=0+4(x)0+1

1=4(x)0+1

1=0+1

1=1

substitution for (-3,-2)

y=x+1

-2=-3+1

-2=-2

its line 2 i just added the rest or else it wouldn't let me answer
