<h3>Definition of terms</h3>
- Negative sections of the graph: They are the parts where the graph is below the x-axis. That is option C.
- End behaviour: This is what happens to the graph on the far left or far right. That is option E.
- Positive sections of the graph: This is the parts where the graph is above the x-axis. That is option D.
- Intercepts: This is the points where the graph crosses an axis. That is option B
- Relative extrema: This is the points of relative minimum or maximum in a graph. That is option A.

Answer:
csc (- 30)° = - 2
Step-by-step explanation:
Using the trigonometric relationship
csc x = 
and the exact value sin30° = 
sin(- 30)° = - sin30° = - , thus
csc (- 30)° = 
= - 2
Answer:
Step-by-step explanation:
1. If m<2 = 32°
the measure for m<4 is 148°
x + 32° = 180°
x = 148°
measure of m<6 = 148° alternate interior of m<4
2. If m<1 = 65°, then m<2 and m<3 are also 65°
Both m<2 and m<3 are vertical angles therefore they are 65°
m<1 and m<2 are corresponding angles therefore they are 65°
