Jonathan and Timothy are playing on a seesaw during recess. The height, in feet, of Timothy after x seconds is represented by the graph below.


The function describing this graph is a transformation of the parent cosine function, y = cos x. Which interval best describes the range of the transformed function?

A. [0, 8]

B.[0, 6]

C. [0, 2]

D.[0, 4]


Again, sorry for not being able to have the graph, but I really need help. It's from plato.

Answer:

D.

Step-by-step explanation:

Answer:

D. [0,4]

Step-by-step explanation:

We are provided with the graph of height of seesaw with respect to time.

The new graph is transformed from the function y = cosx,

It is required to find the range of the transformed function.

Now, as we know the range (i.e. the values where y varies) of cosx is [-1,1] and the new function is a transformed version of cosine function.

So, the values of y are varying from minimum value 0 to maximum value 4 in the given graph.

Hence, the range of the transformed function is [0,4].
