The domain is the input values, which would be the numbers that have the arrows pointing away from them.
This would be the 4 numbers in the oval on the left side.
The answer is B. {1,2,3,4}
Answer:
35
Step-by-step explanation:
The entire angle is 70 degrees. If it is an angle Bi (which means two) sector, then divide it by two, which becomes 35 degrees.
Answer:
b = 7
Step-by-step explanation:
3(b−4) + 5b = 44
3b - 12 + 5b = 44
8b = 44 + 12
8b = 56
b = 56/8
b = 7
Answer:
D: y=2|x|-1
Step-by-step explanation:
We need to find the equation which describes the graph
The general form of equation for this graph is y=|x|
The graph opens upwards so its positive
We cannot choose option (a) and option (d) because it has -2
Lets check with option b and d
In the graph, the y values starts at -1. (0,-1) is the vertex.
Lets plug in (0,-1) and check with option b
y=2|x|+1
-1= 2|0|+1
-1=+1, its false.
Lets check with option (d)
y=2|x|-1
-1= 2|0|-1
-1=-1, its true
Option D is the answer
