A science teacher wrote the table of values below. Amount of Hydrogen vs. pH Amount of Hydrogen, x (in moles per liter) pH, f(x) One-tenth 1 StartFraction 1 Over 100 EndFraction 2 StartFraction 1 Over 1000 EndFraction 3 StartFraction 1 Over 10,000 EndFraction 4 StartFraction 1 Over 100,000 EndFraction 5 Which function models the data in the table? f (x) = StartFraction 1 Over x EndFraction, x not-equals 0 f (x) = log StartFraction 1 Over x squared EndFraction, x not-equals 0 f (x) = log StartFraction 1 Over x EndFraction, x not-equals 0 f (x) = StartFraction 1 Over x squared EndFraction, x not-equals 0
