Can somebody help me wit this? Find the range and the domain of: f(x)=(1/2)|x-2| The domain is all real numbers (x) from -infinity to infinity The range (of f(x)) is 0 to infinity, since it can never be negative. f(x) has a minimum value of zero when x=2.

Ok I got another one I can figure out 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.

Hello again, I am now working on trying to find the relation of x = 1 - y^2, along with the domain and range. Then written in interval notation. I think I am ok with figuring out the domain and range on a graph but my problem is how to solve to get these x and y coordinates. ...

An exponential function with a base of 3 has been vertically stretched by a factor of 1.5 and reflected in the y-axis. Its asymptote is the line y=2. Its y-intercept is (0,3.5). Write an equation of the function and state its domain and range.

how do i find the domain and range of equations? example: f(x)=ab.solute value of x-3. f(x)=square root 36-x^2 g(x)=-2x+2. do i find the range by pluggin in y for the x and then solving. for example: x=-2y+2, and then i get y=x-2/-2. and then is that how i find the range...
