Answer:
with x
Step-by-step explanation:
Answer:
1. cos (x/2)
2.y=cos(4x)
3. y=cos(x)
4.y= cos(x/4)
Step-by-step explanation:
The graph of cosine function is sinusoidal and the y value ranges between -1 to 1.
the cosine function is periodic with general period P of 2π
if P< 2π then cosine graph experience a compression horizontally
if P>2π then cosine graph experience a stretch horizontally
for graph 1, the period is 4π hence the graph is stretched with period of 4π
for graph 2, the period is π/2 hence the graph is compressed with period of π/2
for graph 3, the period is 2π hence the graph is periodic with period of 2π
for graph 4, the period is 8π hence the graph is stretched with period of 4π

Answer:
A is correct don't you know
Answer:
72
you have to add five and thirteen to get eighteen then subtract 90 by 18 and get 72
Any fraction that would simplify down to -3/7
Remember, what you do to the denominator, you must do to the numerator.
For example:
-6/14 is an answer choice, for: (-6/14)/(2/2) = (-3/7)
Hope this helps
