The multiplier to get from 6 * ... to 15 is 15/6.
If 6 * 15/6 = 15, then 20 * 15/6 = 50, answer B.
Considering their concepts, on the graph of a function, the domain and the range are given as follows:
- Domain: Horizontal axis, values of x.
- Range: Vertical axis, values of y.
<h3>What are the domain and the range of a function?</h3>
- The domain of a function is the set that contains all the values of the input.
- The range of a function is the set that contains all the values of the output.
In a graph, the horizontal axis represents the input and the vertical axis represents the output, hence the domain and the range are given as follows:
- Domain: Horizontal axis, values of x.
- Range: Vertical axis, values of y.
