I am assuming you meant to write b(x) = x-4.
Since this is a linear function, the domain is all real numbers.
Could you show us the picture or there isn’t one ?
Answer: "less than" = subtract ( x - y )
So in this case its is 5-9 = -4 or 9-5=4.
Answer:
(-∞,0)
Step-by-step explanation:
Graph y=|x|
Note that the graph is shaped like a V. The left half of the graph is decreasing from -∞ up until 0 when it hits the origin and starts to increase. Put this into interval notation: (-∞,0).
