I think it’s A because 4*2 is 8 and if n were quadrupled it would be 2
To be a function every input value (x) can only have one output value (y)
On the graph there are 2 out put values for x = 2 so it is not a function.
The answer would be C.
Answer:
x ≤ - 5
Step-by-step explanation:
Given
- 2x - 1 ≥ 9 ( add 1 to both sides )
- 2x ≥ 10
Divide both sides by - 2, reversing the symbol as a result of dividing by a negative quantity.
x ≤ - 5
