Question

What are the domain and range of f(x) = 2|x – 4|? domain: x <= 2; range: (-infinity,infinity) domain: (-infinity,infinity); range: f(x)>= 0 domain:(-infinity,infinity); range: f(x) <= 0 domain: x>= 2; range: (-infinity,infinity)

Answer 1

Answer:

domain: (-infinity,infinity);

range: f(x)>= 0

Step-by-step explanation:

f(x) = 2|x – 4|

The domain is the input values or the values that x can take

We can use any value we want for x

Domain: -infinity to infinity

The range is the output values

Since it is an absolute value, the smallest value it can take is 0, it can increase as large as it wants

Range: 0, infinity

Answer 2

Answer:

domain is (-infinity, infinity);

range is f(x)>= 0
