I have to find the domain and range for the composite of functions G(x)=sinx and h(x)=x^2-x+1. I'm confused about this and would really appreciate some help. Thanks.

how would i go about finding the domain of the function f(x)=(3x+1)/(sqrt(x^2+x-2)) and both the domain and range of g(x)=(5x-3)/(2x+1)

this website would be very helpful for your problem,since I can't paste an internet address just go to google and search domain of a function and click on the first one. It's all about finding the domain and range of a function.

The domain of y=f(x) is the range of values of x such that f(x) exists. We know that the ln() function does not admit negative arguments, so the domain of f(x) consist of the ranges of x which makes x^2-4x non-negative, or x^2-4x≥0 .... (1) The solution to equation (1) is ...

Given the following function rules and domains, find the associated ranges. (a) f(x) = 2x +3, Domain = {0, 1, 2} (b) f(x) = 0, Domain = {0, 1, 2} (c) f(x) = 2x + x2, Domain = {1, 0, 2}

in plain English, the domain is the value of x that you may use in your given function to return a value in your first one, remember that we cannot divide by zero, so x=0 is the only value which would not work so the domain would be the set of real numbers, except x is not ...

how would this equation look: y=f(x+3) when y=f(x)= x^2 would it look like so.... x^2(x+3) adam, there's a slight problem with your notation in the expression y = f(x+3). Ordinarily we wouldn't put an expression in place of a variable, unless we were making what is termed a ...
