What is the domain of the function y=x-1 ​

Mathematics
1 answer:
Amiraneli [1.4K]2 years ago
8 0

Answer:

All rational numbers or all numbers

Step-by-step explanation:

The function is a linear positive slope equation, which looks like the screenie below. Lines always travel forever, and since it is a linear line with a slope, it will be forever going in both directions.

Domain is the x-values that a function has, while range is the y-values.

Since the domain and range are infinite, it is all real numbers.

Hope this helps!

This is the concept of scale factor. The linear scale factor is given by:
(height of sculpture)/(height of clothespin)
=20/(5/12)
=48
Given that a woman is 5ft 7 in, the sculpture of this woman would be:
height of sculpture=(scale factor)*(height of the woman)
height of the woman=5 ft 7 inches=5 7/12 ft=67/12 ft
hence the height of the sculpture will be:
67/12×48
=268 ft
