What general statement can you use to determine the ordered pairs of the vertices of a figure if it is reflected across the y-axis?
a.
if a figure is reflected across the y-axis, the x-coordinates of the vertices in the reflection will be the same as those in the original figure and the y-coordinates of the vertices in the reflection will be the opposite of those in the original figure.
b.
if a figure is reflected across the y-axis, the x-coordinates of the vertices in the reflection will be the opposite of those in the original figure and the y-coordinates of the vertices in the reflection will be the same as those in the original figure.
c.
if a figure is reflected across the y-axis, the x-coordinates of the vertices in the reflection will be the opposite of those in the original figure and the y-coordinates of the vertices in the reflection will also be the opposite as those in the original figure.

B

Step-by-step explanation:

Reflection across y- axis: The transformation rule is given by

There are x- coordinate change into negative x- coordinate  and y coordinate remain same after reflection.

If a figure is reflected across the y- axis then the y- coordinate of the vertices  in the reflection will be the  same as those in the original figure and x- coordinates of the vertices in the reflection will be opposite of those in the original figure

Hence, option B is true.

first option

a function is a relation in which an input is paired with exactly one output.

so, let's find the right answer.

in our first option, our inputs are january, february, and march. the outputs are 30, 28, and 25. each input has it's own output. this is correct!

our second option we know is incorrect, because ms. valverade has two outputs, dogs and cats. this is not a function.

our third option is incorrect as well. the yellow square has two ouputs, the square and the triangle.

lastly, in our fourth option, we see the number 7 two times with a different output. therefore, this is not a function.

remember: each input must be paired with only one output!
