Every function associates input values with output values. The domain of a function is the set of all the inputs the function accepts.
You will basically always find your function graphed with the inputs on the horizontal axis and the outputs on the vertical axis. This means that every point on the graph has coordinates , and the domain is the set of all the x values.
The points on your red line have all coordinates , where d starts from 0 and ranges up to 12. So, the domain of the function is

2 1/7 is converted toan improper fraction as 15/7.
What are improper fractions?
- A fraction that has the numerator higher than or equal to the denominator is said to be inappropriate.
- A fraction, such as 5/4, is when the numerator exceeds the denominator.
- Examples are 9/2, 8/5, 10/3, etc.
- Multiply the denominator by the full number to find the improper fraction's numerator.
- Add this to the numerator after that.
- The same will apply to the denominator.
So, the given fraction is:
- 2 1/7
Now, convert it to an improper fraction as follows:
- 2 1/7
- 14+1/7
- 15/7
Therefore, 2 1/7 is converted to an improper fraction as 15/7.

Answer:
Yes, (8,32) lie on the line y=4x
Solution:
Given equation of line
y=4x ---- eqn 1
Any point lie on the line if that point satisfies the equation of line.
So from question given point is (8, 32) that is x=8 and y=32
On substituting x=8 and y=32 in equation (1)
32 = 4(8)
32 = 32
Since Left hand side is equal right hand side, the points (8,32) satisfies the equation of line y = 4x
Hence (8,32) lie on the line y=4x
Answer: yes it does
Step-by-step explanation:
Ordered pair: (8,32)
y=4x
32= 4(8)
32 = 32
