Algebra II
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). ...

Algebra 1
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 ...

y= X^2 + X - 500/10 and y is the number of milliliters of fuel consumed per second and X is the speed of the engine in revolutions per minute. If the engine operates between 100 revolutions per minute and 400 revolutions per minute what is the domain and range Is this correct...

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- is my answer right
The one-to-one function f is defined by f(x)=(4x-1)/(x+7). Find f^-1, the inverse of f. Then, give the domain and range of f^-1 using interval notation. f^-1(x)= Domain (f^-1)= Range (f^-1)= Any help is greatly appreciated. Algebra - helper, Wednesday, February 2, 2011 at 7:...

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.

Let f(x)=11/x+7 with the domain [-2,3]. Find the d
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/...

f(x)=√x-2 Find the domain of the function is it x-2 the range of function is it (00,-2) the domain of the inverse is it x>-2 The range of the inverse is it (-2,00) Thanks

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.
