Over which interval is the graph of the parent absolute value function f(x)=|x| decreasing?
1 answer:
Answer:
(–∞, 0)
Step-by-step explanation:
The graph of the absolute value parent function f(x) = |x| is shown in the attached diagram.
We can clearly see that from -∞ to 0, the function is decreasing and from 0 to +∞, it is increasing. This is the basic, parent absolute value function.
THe questions asks, when is it decreasing, so clearly, it is from -∞ to 0.
This is the answer.

Answer:
a ≠ 2
Step-by-step explanation:
Given
The denominator of the rational function cannot be zero as this would make it undefined. Equating the denominator to zero and solving gives the value that a cannot be, that is
- 3a + 6 = 0 ( subtract 6 from both sides )
- 3a = - 6 ( divide both sides by - 3 )
a = 2 ← excluded value
Answer:
16
Step-by-step explanation:
Substituting 16 will make the expression valid and correct since the square of -4 is 16 and the addition of it is -8.
