The function is given by the formula f (x) = 4-x / 3 which of the given equalities is wrong. F (-3) = 5 F (12) = 0 F (1) = 3 1/3 F (0) = 4

f (x) = 4 – x / 3

f (-3) = 4 – (-3) / 3 = 4 – (-1) = 4 + 1 = 5,
f (-3) = 5.
This equality is true.

f (12) = 4 – 12/3 = 4 – 4 = 0,
f (12) = 0.
This equality is true.

f (1) = 4 – 3/3 = 4 – 1 = 3,
f (1) = 3 ≠ 3⅓.
This equality is not true.

f (0) = 4 – 0/3 = 4,
f (0) = 4.
This equality is true.

Answer: the equality f (1) = 3⅓ is not true.
