$→x + 9 = 2(2x - 3)$

$→x + 9 = 4x - 6$

$→ 4x - x = 9 +6$

$→ 3x = 15$

$→ x = 5$

Answer:

the period of this graph is 2 $\pi$

Step-by-step explanation:

The period is the length of the section that repeats. So for this graph, we need to calculate the distance between 2 peaks or 2 troughs of the curve.

Let's look at the peaks (maximums).

One is at x = 0 and the next is at x = 2 $\pi$

2 $\pi$ - 0 = 2 $\pi$

Therefore, the period of this graph is 2 $\pi$
