Question

Which answer describes the restrictions for the variables?

x - 4 / x + 1

Answer 1

4x/ 1x = 4

`4X/1+ 2`

Answer 2

restrictions are not allowed values

the most common restrictions are sqrt of a negative and dividng by zero
since there are no sqrts in this quesiton, see whicch value of x will make us divide by zero
x-4/x+1
denom=0 to find restricted value
x+1=0
minus 1
x=-1

the restricted value is x=-1
basically
x=all real numbers except for -1
