To find the zeros of the quadratic function \( y = -5x^2 + 16x \), we set \( y \) equal to zero:

\[ 0 = -5x^2 + 16x \]

Next, we can factor the equation:

\[ 0 = x(-5x + 16) \]

Setting each factor to zero gives:

  1. \( x = 0 \)
  2. \( -5x + 16 = 0 \)

From the second equation, we solve for \( x \):

\[ -5x + 16 = 0 \ 5x = 16 \ x = \frac{16}{5} = 3.2 \]

Thus, the zeros of the function are \( x = 0 \) and \( x = 3.2 \).

The corresponding points where \( y = 0 \) are:

  • \( (0, 0) \)
  • \( (3.2, 0) \)

Therefore, the correct response is:

\((0, 0)\) and \((3.2, 0)\)
