How would you solve this f(x)⁄g(x) problem (please include ALL steps and an explanation for each)? f(x)=(5x+11)/(x2-9) g(x)= (4x-2)/(x2-9) Also, would...

For horizontal compressions, I know you do it if x is greater than 1, but do you divide or multiply the x value by the c value? Why would it be a vertical compression of c? So...

So if f(x)=√(x-3), I know the original domain would be [3, ∞) and the range would be [0,∞), but what would the domain and the range be for the inverse be, which is f-1=x2+3, and why...

How would you find the domain for f(x) = 2x - 4x^1/2 + 2 ? I'm not exactly sure what to do/what steps to take. Do you factor out a 2x1/2 from the whole problem and then get 2x1/2 times x2-3x+2...
