ANSWER
Period: 2π , amplitude: 4
EXPLANATION
The graphed function is

The amplitude of this function is

The period is 2π because there is no phase shift hence the period is still equal to the parent function.
Period: 2π , amplitude: 4
Answer:
10
Step-by-step explanation:
1x^3-2x^2-4x-6
x^3-2x^2-4x-6
(4)^3-2(4)^2-4(4)-6
64-2(16)-16-6
64-32-16-6
32-16-6
16-6
10
So when x=4, the output will be 10
