Question

What is the range of f(x)?

Answer 1

Answer:

$\{f(x)\ |\ -\infty$

Step-by-step explanation:

The range of the function are all possible values of f(x).

From the diagram you can see that

• for all $x\le 0,$ the value of f(x) is always 4;
• for $x\ge 0,$ the value of f(x) decreases from 4.

This means that the range of the function f(x) is

$\{f(x)\ |\ -\infty$
