The graph of a periodic function f is shown below. What is the period of f?
   

What is the midline for f?
y=

What is the amplitude of f?
   

Write a function formula for f. (Enter "theta" for θ.)
f(θ)=

​

(1, –1), (16, –4), (36, –6)

step-by-step explanation:

given that the function is

this can also be written as

we have to graph this function and check which list of points lie on the graph

see attachment for graph:

we find that the points lying are (1,-1) (16,-4) and (36,-6)

since square root is there we find that x can only be posiitve but y can be since square root both positive and negative.

the first option is the answer.
