Answer:
The function that is shown in the graph is:
y= -cos x
Step-by-step explanation:
We are given a graph of a function we have to recognize which function is represented by the given graph.
Clearly we could observe from the graph that the function takes the value -1 at x=0.
Hence, the function which satisfy this condition is:
( since at x=0
y= -cos 0=-1
Also at x=π
we get
y= -cos(π)=-(-1)=1
similarly at x= -π
we get:
y= -cos(-π)= -(-1)=1)

C) 17
Using the rule
A^2 + B^2 = C^2
8^2 + 15^2 = x^2
64 + 225 = x^2
x^2 = 289
x= _/-289
x = 17
