Question

The graph of an absolute value function opens down and has a vertex of (-3,0).

The domain of the function is

A) [-3,∞)
B) (-∞,0]
C) (-∞,∞)

The range of the function is

A) [-3,∞)
B) (-∞,0]
C) (-∞,∞)

Answer 1

your correct answe is the 1 b sec is a

Answer 2

Absolute value graphs always look like the letter V .They can open up or down.

Domain is set of values x can take .For any absolute value function x can take any value .We can say

The domain of the function is

C) (-∞,∞)

If the graph opens downward, the range will be less than or equal to the y-coordinate of the vertex. The y coordinate is 0 so Range will be less than 0.

The range of the function is

B) (-∞,0]
