Question

What is the range of the absolute value function below?

f(x) > -4
f(x) > -1
f(x) < 1
f(x) < 4

Answer 1

f(x) < 1

Explanation:

Max y value on the graph is y = 1, hence the range is f(x)《 1

From the given options,

f(x) < 1

Answer 2

y ≤1

Explanation:

The range is the output values

It has a max at 1 and can be any value below 1

y ≤1
