Question

graph each function;
1.h(X)=2|x|,where the domain is {-1,0,1,2}
2.f(X)=x-1, where the domain is {x|x is a real #]

Answer 1

1. hmmm. Im not sure what the domain brackets mean. is it set notation?

usually wouldn't it just have two values? like: [-1,1] to show from -1 to 1 ?

2. again, im confused by the brackets. But ignoring that, it' should just be the same as y=x except that it is shifted down 1

Answer 2

All the first one does is make it thinner. So the "v" won't be as wide.

Answer 3

But I agree, the {}'s are confusing.
