How would you solve this problem: Slove y=1/4-1 if the domain is(-4,-2,0,2,4) Could someone please explain to me how to do this? Thank You in advance for your help!

Should there be an x in that equation?

If so, be careful about parentheses

y = (1/4) x - 1

y = 1/(4x) -1

y = 1/(4x-1)

which

If the last, x = 1/4 is not in the domain

If the second, x = 0 is not in the domain

otherwise just put those 5 discrete values in for x and the five values of y are your results.
