Answer 3

How in the world do I survive life

Answer 4

Jk so this problem is asking you to find the solutions in that formula.
For example, if you plug -1 into the equation, you don’t get -1 as an result, so -1 is not an answer of that question, it’s just asking what number x when plugged in the equation f would equal x as the result as well

Answer 5

Try all the other numbers, it’s not B. If you plug in -2, you get 2/3 and those two are not the same.

Answer 6

Oof. Someone gave me warnings not to give answers. I wonder who. Hmmmm.

Answer 7

The rule of question cove is to help someone out lmao

Answer 8

Ik

Answer 9

so D?

Answer 10

2/-2+1 = -1

2/2+1 = 2

Answer 11

remember order of operations

2/(2+1) is 2/3, not 2

Answer 12

so using process of elimination, any answer with 2 in it must not work, so B, D, and E are out

when you plug in x = -1, do you also get -1 as the result?

Answer 13

no

Answer 14

i get 0

Answer 15

awesome, so A doesn't work either

using process of elimination that narrows us down to C as the only possibility

you can verify this yourself by plugging in x = -2 to give f(x) = -2 and x = 1 to give f(x) = 1

Answer 16

got it thank you all!
