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:
51.84 centimeters
Step-by-step explanation:
I think that the answer that is highlighted in blue is correct. I am not sure for this one. But, “both the table and graph are proportional” seems correct.

Answer:
Depending on what the equation is (see below for options) answers are:
or -1,1=x
Step-by-step explanation:
Two possibilities are present:
- The base of an exponential function is the number raised to an exponent of x.
. The base here is 3/8. To find when f(x) = 3, then substitute and solve. 
- If this is a quadratic function then it has a base of x.
. To find when f(x) = 3 then substitute and solve.
