Question

Connor is using a computer program to graph the function
J(n) = –13n – 421. He wants to see the intercepts.

Which minimum values should he use to set up the viewing window?


A. X Min: –40, Y Min: –500

B. X Min: –25, Y Min: –400

C. X Min: –400, Y Min: –25

D. X Min: –500, Y Min: –40

Answer 1

I think A?

Answer 2

J(n) = -13n - 421
y = -13n - 421

the y intercept is -421
the x intercept can be found by subbing in 0 for y
0 = -13n - 421
13n = -421
n = -421/13
n = -32 and 5/13

So I am getting x intercept as -32 5/13 and y int as -421....but I am not real sure of the answer...sorry

Answer 3

I am thinking B

Answer 4

Thank's for solving for me, appreciate that. I got 32.38 so I thinking A? If not that's not right its okay, thanks for helping

Answer 5

Just saw your post, So B? ok

Answer 6

because with negatives the smaller number is bigger

Answer 7

ok thanks, I have two more questions Do you mind helping? If you have something else to do I understand

Answer 8

I can try to help...can't make no promises that I will know the answer

Answer 9

Great, ok thanks
