Determining if Points Belong to the Graph of a Function

To determine if the given points belong to the graph of the function y = 8/x, we can substitute the x-coordinate of each point into the function and check if the resulting y-coordinate matches the given y-coordinate.

Let's evaluate each point:

1. Point A(-1, 8): - Substituting x = -1 into the function, we get y = 8/(-1) = -8. - The y-coordinate of point A is 8, which does not match the calculated value of -8. - Therefore, point A does not belong to the graph of the function.

2. Point B(4, 32): - Substituting x = 4 into the function, we get y = 8/4 = 2. - The y-coordinate of point B is 32, which does not match the calculated value of 2. - Therefore, point B does not belong to the graph of the function.

3. Point C(4, 2): - Substituting x = 4 into the function, we get y = 8/4 = 2. - The y-coordinate of point C is 2, which matches the calculated value of 2. - Therefore, point C belongs to the graph of the function.

4. Point D(8, 2): - Substituting x = 8 into the function, we get y = 8/8 = 1. - The y-coordinate of point D is 2, which does not match the calculated value of 1. - Therefore, point D does not belong to the graph of the function.

In summary: - Point A(-1, 8) does not belong to the graph of the function. - Point B(4, 32) does not belong to the graph of the function. - Point C(4, 2) belongs to the graph of the function. - Point D(8, 2) does not belong to the graph of the function.
