Answer: 2.339
Step-by-step explanation:
Make sure that you align your decimal points. The 1 shouldn't line up with the 7.
Instead, write your equation like:
2.37
- 0.031
The numbers don't match up, but instead, the decimals do.
I hope this helps! :)
Answer:
-2pi/3
Step-by-step explanation:
y = 2 cos 3(x + 2π∕3) +1
y = A sin(B(x + C)) + D
amplitude is A
period is 2π/B
phase shift is C (positive is to the left)
vertical shift is D
We have a shift to the left of 2 pi /3
