Question

For the graph find a) b) c) and d)

Answer 1

Answer:

$f(0) = -1$

$f(\pi) = 1$

Domain: All real numbers

$Range = [-1,1]$

Step-by-step 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:

$Range = [-1,1]$
