No, it won't be. A function is determined by two collections A and B and an assignment of a unique element of B to each element of A. If you let the function be f(x) = x, and let the domain be -1 to +1, then the range will be 0 to +1. But if you swap the domain and the range ...

I don't think it should matter. Perhaps your teacher might have some requirement. The answers are -4 and 6. These are both domain values for the function. When expressing domain and range values in a function, the x and y values are shown as (x,y) indicating (domain, range). ...

You should have an idea what f(x) = 3^x looks like its domain is any real number of x the range is y>0 so you have f(x) = 3^x - 4 , which just drops the curve down 4 units the domain is still x ∈ R , the domain is y > -4 if you meant: f(x) = 3^(x-4) , then y = 3^x ...

I'd say no. The range of a function is the domain of its inverse. g(f) = x the domain of g is the range of f.

**Algebra**

domain: any real number range: any real number > 0 for the domain of the inverse function, since you interchange the x and the y, the range of the old becomes the domain of the inverse, and vice versa.

**how to find domain and range**

domain is where denominator is not zero: all reals except x = -1/2 Since there is a single vertical asymptote, and a horizontal asymptote at y=-4, the graph does not cross the line y=-4, and the range is all reals except y=-4.

In the original: if x= -2 , y = 11/5 if x = 3, y = 11/10 So the curve is continuous from (-2,11/5) to (3,11/10) in the inverse the domain of the original becomes the range of the inverse, and the range of the original becomes the domain of the inverse domain of inverse : [11/...

**Math for educators**

I think the reason is asking you this because your question makes little sense. When looking for domain and range you are usually working with ordered pairs (x,y) (3,4). Unless you mean range as in Central Tendency, but taht wouldn't have a domain.
