I posted a problem earlier and made a mistake the question is what is the domain and range of f(x)= log subscript 3 (1-x)? Sorry! The answer is the same. The domain and range will be the same as if it were log base 40.

Ok so g ° f = {(1, 4), (2, 2), (3, 2), (4,3)} There are two 1s in the range of f(x) though (1,2) and (3,1). . .Does that mean anything? Is this correct: Does g ° h = {(1, 2), (2?, 2?), (3, 2), (4, 1)}? For this one there was no 2 in the range of h. Also, for h^2 = h &...

the domain is the set of first elements, the range is the set of second elements, so the domain is {3} and the range is {9,10,11,12}

whats the domain and range of sine and tan? The sine ranges from -1 to +1. Its domain is all postive and negative numbers. I will be happy to critique your thinking on tangent.

calculus
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) ...

Now, think of a set of domain and range from your own life. Write a paragraph on whether you think your particular domain and range is or is not a function and why. I need a life a example? is it a function?

Set theory
Correction for range, which is the set of all values produced by the function within the given domain. For the above relation f(x)=y=x2+1, the domain is {1,2,3,4,5} the range is {2,5,10,17,26} The inverse is as above.

math
The domain of the inverse of h(x) is the range of h(x). The range of h(x) is (3, infinity), as h(x) is never less than 3. Therefore, the domain of the inverse is (3, infinity)
