Point d ( −1, 5 ) is reflected across the x-axis. which statements about d′ are true? select each correct answer. the x-coordinate is 1. the y-coordinate is 5. the y-coordinate is −5. the x-coordinate is −1.

The correct options are 3 and 4.

Step-by-step explanation:

Given information: Point D ( −1, 5 ) is reflected across the x-axis.

If a point reflected across x-axis, then

The coordinate of point D are (-1,5).

The coordinates of point D after reflection across x-axis are

The x-coordinate of D' = -1

The y-coordinate of D' = -5

Therefore the correct options are 3 and 4.

the circle graph is not a function.

step-by-step explanation:

the graph of the circle is not a function.

because for a graph to be a function, each value of x must give one value of y

in the circle, the values of x for -2< x< 2 each give 2 values of y.

hence this is not a function.
