Peter reflected trapezoid ABCD across the y-axis. If angle A is 115° and angle B is 65°, what is the degree measurement of angle A′?

Step-by-step explanation:

Given

Reflected across y-axis

Required

The measure of A'

Reflection is a kind of rigid transformation. This means that, it doesn't affect the measure of length and angles after it is carried out.

So, when ABCD is reflected, the measure os each angle remains the same.

Hence:

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.

step-by-step explanation:

just count the values of x & y of the vertex of the graph and see how many units in the x and y direction will get you from the f(x) graph to the f(x) graph
