Answer:

  input: 0 or -4

Step-by-step explanation:

Given:

  c(y) = y² +4y

Find:

  y such that c(y) = 0

Solution:

  0 = y² +4y . . . . . desired condition

  0 = y(y +4) . . . . . factor

We have the product of two factors. The "zero product rule" tells us that the product is only zero if one or more of the factors is zero.

  y = 0 . . . . . makes the factor y be zero

  y = -4 . . . . . makes the factor (y+4) be zero

The inputs you're looking for are 0 or -4.
