Answer:
B. -∞ < y < 2
Step-by-step explanation:
The range is the vertical extent of the graph,
The arrow pointing down means the graph extends to -∞ at the lower end. The flat at y=2 means there is a horizontal asymptote there, and the upper limit of the range is 2.
-∞ < y < 2 . . . . . matches choice B
Im pretty sure that the answer is A.18 because it goes into all of the numbers :)
3. opposite sides congruent
4. same angle theorem
5. reflexive theorem
6. angle side angle theorem
The amplitude is the highest the function ever gets. That happens when the
cosine is ' 1 '. At that point, the value of the function is<em> 5/2 </em>.
The period is the first time after zero that the angle in the cosine is 2π .
x/2 = 2π
Multiply each side by 2 : x = 4π
The period is <em>4π .</em>
