Answer 3

I can help you with your math question.

The graph of the function $y=\sqrt{x}$ is a curve that starts from the origin and goes up and to the right. To check if a point lies on the graph, we need to substitute the x-coordinate of the point into the function and see if the result is equal to the y-coordinate of the point.

For example, for point A(16, 4), we have:

$y=\sqrt{x}$

$y=\sqrt{16}$

$y=4$

Since the y-coordinate of point A is also 4, we can conclude that point A lies on the graph.

We can repeat this process for the other points:

- For point B(16, -4), we have:

$y=\sqrt{x}$

$y=\sqrt{16}$

$y=4$

Since the y-coordinate of point B is -4, which is not equal to 4, we can conclude that point B does not lie on the graph.

- For point C(0.09, 0.3), we have:

$y=\sqrt{x}$

$y=\sqrt{0.09}$

$y=0.3$

Since the y-coordinate of point C is also 0.3, we can conclude that point C lies on the graph.

- For point D(-25, 5), we have:

$y=\sqrt{x}$

$y=\sqrt{-25}$

$y$ is not a real number

Since the x-coordinate of point D is negative, we cannot find a real value for y. Therefore, point D does not lie on the graph.

In summary, only points A and C lie on the graph of the function $y=\sqrt{x}$. I hope this helps you understand the problem. If you have any other questions, feel free to ask me.Ответь+подробно.+Какие+из+точек+А(16;+4)+В(+16;+-4)+С(+0,09;+0,3)+D(-25;+5)+лежат+на+графике+функции+у=√х+?
