There are no zeros.

Answer 1

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

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

We can factor this equation:

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

Setting each factor equal to zero gives us the solutions:

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

Solving for \( x \) in the second equation:

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

Thus, the zeros of the function are:

\[
x = 0 \text{ and } x = 3.2
\]

This means the points are \( (0, 0) \) and \( (3.2, 0) \).

Therefore, the correct response is:

\[
(0,0)(3.2,0)
\]

So the answer is \( \left(0, 0\right) \) and \( \left(3.2, 0\right) \).
