basically solving the equation 4z+1=0 will give you your answer

opposite of tht my bad
freckles
  • freckles
you mean reciprocal of that?
anonymous
  • anonymous
yes
freckles
  • freckles
opposite means just changing the sign :p
freckles
  • freckles
but yes the only value z can't be for this function is -1/4 since it means we would be dividing by 0 here
anonymous
  • anonymous
so then just 4/-1 = -4
freckles
  • freckles
oh I thought you meant reciprocal of -4/1
anonymous
  • anonymous
oh lol
freckles
  • freckles
which is -1/4

4z+1=0 subtract 1 on both sides 4z=-1 do you know you are going to divide both sides by 4 right?
anonymous
  • anonymous
yes so the 4 in 4z gets cancelled out & whats left is z = -1/4
freckles
  • freckles
dividing both sides by 4 4z/4=-1/4 4/4=1 so you can say you canceled on the factors of 4 on top and bottom on the left hand side giving you z=-1/4
freckles
  • freckles
which is the reciprocal of -4/1 aka -4 so I kind of thought that was you meant
freckles
  • freckles
anyways yes the fraction is undefined at z=-1/4 because it means we would be diving by 0 if we plug it in.
