Step-by-step explanation

Given the function:

$f(x)=2\sin x$

we can choose any value between the interval –2π < x < 2π. For example, –π, –π/2, 0, π/2, and π.

• x = –,π

$f(\pi)=2\sin(\pi)=2\cdot0=0$

The coordinate is (–π, 0).

• x = –,π/2

$f(-(\pi)/(2))=2\sin(-(\pi)/(2))=2\cdot-1=-2$

The coordinate is (–π/2, –2).

• x = 0

$f(0)=2\cdot\sin(0)=2\cdot0=0$

The coordinate is (0, 0).

• x = ,π/2

$f((\pi)/(2))=2\cdot\sin((\pi)/(2))=2\cdot1=2$

The coordinate is (π/2, 2).

• x = ,π

$f(\pi)=2\cdot\sin(\pi)=2\cdot0=0$

The coordinate is (π, 0).

Answer

Thus, our table of values is:

Finally, graphing the points calculated in the table:
