Answer:
Step-by-step explanation:
The domain is all possible values for x.
The range is all possible values for f(x) or y.
The domain given is {-3, -2, -1, 1}.
Plug x as {-3, -2, -1, 1} and find the f(x) or y values.
The range is {7, 6, 5, 3}, when the domain is {-3, -2, -1, 1}.
If you think about this equation as a line, then in order to have an infinite number of solutions is to have another equation that describes the same line.
So, for example 3y=2x-15 would be one of those.
The correct answer is B. cm3
This is saying "centimeters cubed", and is true because you are multiplying 3 dimensions of centimeters, width*length*height, to get the answer. Thus, you are multiplying the numbers <em>and </em>the units. 30*30*25 and cm*cm*cm
