Question

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)=

Answer 1

period of f?= 4

)midline for f?

y= -1



)What is the amplitude of f?

A= 6/2 = 3

))Function formula is

f(θ)=3 x Cos (π•theta ) - 1
