Part 1: Similarities of sine and cosine graphs are that both has an amplitude of 1 and a period of 2pi.
A differences between sin and cos graphs includes that sin graph passes through point (0, 0).
The required cosine graph is <span>f(x) = 3 cos(4x - 3π/2) + 4</span>
Answer:I can help you round 206834 and 194268 to its nearest thousands place. 207000 would be the estimate for the first number and 194000 would be the estimate for the second number.

Add 9 to both sides:
4x = 36
Divide both sides by 4:
x = 9
