The domain of the function is the value of the independent variable, or simply the x-values. The range is the value of the dependent variable, or the y-values. You can determine its domain and range if the curve of the function passes through their coordinates. Hence,
A. True. If you extend the curve downwards, its opening widens and would then encompass all x-values
B. True.
C. False. This is contradictory to A.
D. True. This is same with B.
E. False. This is contradictory to B.
F. False, the origin is at (0,2). It does not extend upward.
The answers are A, B and D.

Answer:
56
Step-by-step explanation:
Given that there are 8 candidates for student government: Hal, Mary, Ann, Frank, Beth, John, Emily, and Tom.
The three candidates that receive the highest number of votes become candidates for a runoff election.
i.e. 3 persons out of 8 to be selected for becoming candidates for a runoff election.
Since order does not matter we use combinations here
3 persons out of 8 can be done in 8C3 ways
= 56
no of 3-candidate combinations possible are 56

Step-by-step explanation:
True
Your calculator might not be able to perform a "secant" function, but that's because it's easy to convert.
On top of your three basic trig functions (sine, cosine, and tangent) there are three more which act as their reciprocals. (cosecant, secant, and cotangent, respectively)
As review: A reciprocal is when you flip a fraction. For instance, the reciprocal of 2/3 is 3/2. If you have some number that's not a fraction like 5, you can put it as a fraction 5/1 and then get the reciprocal 1/5.
sec(85°) is the reciprocal of cos(85°)
sec(85°) = 1/cos(85°) = 1/0.0871557427 = 11.4737133 <em>(round as needed)</em>
