Answer:
B.) y=csc x
Step-by-step explanation:
The cosecant function has a minimum magnitude of 1, so its range excludes any values in the range -1 < y < 1.
y = csc(x) . . . has a range that does not include -0.8
Given:
The given degree measurement is -60 degrees.
To find:
The radian measure of the given degree measure.
Solution:
We know that,

The radian measure of -60 degrees.


Therefore, the radian measure of the given degree measure is
.
Answer:
In the graph of y = x2, the point (0, 0) is called the vertex. The vertex is the minimum point in a parabola that opens upward. In a parabola that opens downward, the vertex is the maximum point. We can graph a parabola with a different vertex.
