Answer: The amplitude is 4.
Step-by-step explanation:
Given the form of the sine function:

Where
is the amplitude,
is the period and "k" is the vertical shift of the wave.
You know that, in the sine function given (
), you can identify the amplitude and the period. These are:


Therefore, the amplitude of
is:

Answer:
see explanation
Step-by-step explanation:
2 × 
= 2 × 10 × 10 × 10 × 10
= 2 × 100 × 100
= 200 × 100
= 20000
And

= 2 × 2 × 2 × 2
= 4 × 4
= 16
The y- intercept would be 4 units higher
