Answer:


f(0) = -1


f(\pi) = 1

Domain: All real numbers


Range = [-1,1]

Explanation:

Given

The attached graph

Solving (a): f(0)

On the attached graph


f(x) = -1 when
x =0

So:


f(0) = -1

Solving (b): f(pi)

On the attached graph


f(x) = 1 when
x =\pi

So:


f(\pi) = 1

Solving (c): Domain

There is no restriction on x.

Hence, the domain is the set of all real numbers

Solving (d): Range

In the attached graph


y_(min) = -1


y_(max) = 1

So, the range is:


Range = [-1,1]
