You would use 1.73 in order to decrease an amount by 73%
{0, 2, 1/2}
f(h) = 0 when any set of parenthesis equals zero
1. h = 0
2. h - 2 = 0
add 2
h = 2
3. 2h - 1 = 0
Add 1
2h = 1
divide by 2
h = 1/2
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
