Question

A particular sound wave can be graphed using the function

y = 1 sin 2x. Find the amplitude of the function.

Answer 1

Amplitude =1

Explanation:

Given function is
`y=1\cdot\sin\left(2x\right)`.

Now we need to find about what is the amplitude of the given function
`y=1\cdot\sin\left(2x\right)`.

To find that let's compare given equation
`y=1\cdot\sin\left(2x\right)` with standard equation
`y=a\cdot\sin\left(bx-c\right)+d`. We get:

a=1

We know that amplitude of the function
`y=a\cdot\sin\left(bx-c\right)+d` is given by the value of |a|.

Hence amplitude of the given function = |a|= |1|=1
