Answer:

When b= 0.5, the period of orange graph is _4_ pi

When b= 2, the period of orange graph is _1_pi

Step-by-step explanation:

The period of the sinusoidal functions can be easily calculated by observing their graphs.

First, look at the orange graph when b = 0.5

Identify a point where the orange chart cuts the x-axis. For example at [tex]x = 0[/tex]. After completing the rise and fall cycle, the function cuts back to the x axis at [tex]x = 4\pi[/tex].

Then the period [tex]T = 4\pi[/tex].

Second, look at the orange graph when b = 2

Identify a point where the orange chart cuts the x-axis. For example at [tex]x = 0[/tex]. After completing the rise and fall cycle, the function cuts back to the x-axis at [tex]x = \pi[/tex].

Then the period [tex]T = \pi[/tex].

We also know that the period of a sinusoidal function is defined as [tex]T(b) = \frac{2\pi}{b}[/tex]

So:

[tex]T(0.5) = \frac{2\pi}{0.5} = 4\pi\\\\T(2) = \frac{2\pi}{2} = \pi[/tex]

Answer:

Part 2:

Based on this evidence,

When b > 1, the period

✔ decreases

.

When 0 < b < 1, the period

✔ increases

Step-by-step explanation:

This is correct for edge 2020. Hope this helps someone.
