Question

Type the equation for the graph below

Answer 1

Answer:

y = sin3x

Step-by-step explanation:

the equation is of the form y = sinbx

the period of the sine wave is

period = $\frac{2\pi }{b}$ ( b is the coefficient of x )

here period = $\frac{\pi }{3}$ × 2 = $\frac{2\pi }{3}$ , then

$\frac{2\pi }{3}$ = $\frac{2\pi }{b}$ ⇒ b = 3

y = sin3x ← equation of graph
