Hi!
A function is when you can look at any number on the graph, and it only has one value in the line. For example, look at 2 on the y-axis. It only has one point on the line, but -2 on the y-axis has two points on the line. I hope that makes sense.
Therefore the answer is B. No, because some of the y-values are paired with 2 x-values.
Hope this helps! :)

Answer:
The value of x = 15.
Step-by-step explanation:
As shown in the figure the upper half part is 30° and the lower half part is 4 x.
Also from the figure-
<em>30° + 4 x = 90°</em>
<em>4 x = 90° - 30°</em>
<em>4 x = 60°</em>
<em>x = 60°/4</em>
<em>x = 15°</em>
Answer:

Step-by-step explanation:
we know that
An isosceles triangle has two equal sides and two equal interior angles
In this problem
Triangle CDE is an isosceles triangle
because
EC ≅ DE
therefore
----> equation A
Remember that
The sum of the interior angles in any triangle must be equal to 180 degrees
so
----> equation B
---> equation C
substitute equation A and equation C in equation B
