Answer:
A function with a graph that is symmetric about the origin is called an odd function. Note: A function can be neither even nor odd if it does not exhibit either symmetry. For example, f(x)=2x f ( x ) = 2 x is neither even nor odd.

Answer:
∠A=123°.
Step-by-step explanation:
From the given figure it is clear the CD and CE are two tangent lines on circle with center A.
Radius is perpendicular to the tangent at the point of tangency.
Smaller arc DE = (5x-2)°
It means central angle DAE is (5x-2)°.
Now, ADCE is a quadrilateral and sum of all angles of a quadrilateral is 360 degrees.
The value of x is 25.
Therefore, the measure of ∠A is 123°.
