Option 1
Step-by-step explanation:
x⁴ + 2x³ - 5 + 3 + 7x³ + x⁴
2x⁴ + 9x³ -2
Answer:
![y=[1]cos([\frac{2\pi }{3}]x)](https://tex.z-dn.net/?f=y%3D%5B1%5Dcos%28%5B%5Cfrac%7B2%5Cpi%20%7D%7B3%7D%5Dx%29)
Step-by-step explanation:
Looking at the graph, we can see the domain to be from (0 , 2π).
Now we have to find one period that corresponds to cos(x).
The half-period of cos(x) for this graph appears to be pi/3 and adding another pi/3 gets us 2pi/3 to be our cosine period.
b = 2pi/3
a is the same range as cos(x). Range: (0,0)
y = [a] * cos ([b]*x)
y = [1] * cos([2pi/3]x)
Lines K and R, J and Q, L and S, and M and T are all parallel because at no point will they ever intersect.
B is the best. Because she works 8+1 hours 5 times :) hope this helps
