Respuesta :
absolute value graph looks like a V, with the vertex at the origin.
1. the domain (x-values) is: (∞, ∞) TRUE
2. the range (y-values) starts at the vertex: [0, ∞) FALSE
3. the function decreases when left of vertex and increases when right of vertex: decreases (-∞, 0) TRUE
4. f(x) = |x| = +/-x
f(-x) = |-x| = +/-x
f(x) = f(-x) so the function is even TRUE
5. every x-value has a corresponding y-value (there are no gaps) so the function is continuous. TRUE
Answers: 1, 3, 4, 5
Answer:
The correct options are 3, 4 and 5.
Step-by-step explanation:
The parent absolute value function is defined as
[tex]f(x)=|x|[/tex]
where, x is any real number.
The features of the parent absolute value function are :
1. [tex]Domain=(-\infty,\infty)[/tex]
2. [tex]Range=[0,\infty)[/tex]
3. The function decreases on the interval [tex](-\infty,0][/tex].
4. The function increases on the interval [tex][0,\infty)[/tex].
5. The function is even because f(-x)=f(x) for any value of x.
6. The graph of an absolute value function is a V-shaped unbroken curve. So, it is a continuous function.
From the above features we can say that the options 3, 4 and 5 are correct.
