The domain refers to the interval on which the function is defined.
In the case of the graph, the domain refers to all the x-values for which the graph exists.
The graph is defined for x-values greater than 2 but less than or equal to 4 and
x-values greater than or equal to 7.
In interval notation, we have:
(-2,4] and [7,∞).
The second choice is correct:
Answer:
Step-by-step explanation:
<h3>Given </h3>
<h3>To find</h3>
<h3>Solution</h3>
- 5x:9=7:3
- 5x = 7*9/3
- 5x = 7*3
- 5x = 21
- x = 21/5
- x = 4.2
1) they are the same number
the number line part is correct
2) the fraction equals -2.6
make a dot on the 4th and 6th lines to the left of -2
