From Hannah:
Solve y=(1⁄4)x-1 if the domain is (-4,-2,0,2,4).
I don't get how to do this. Can anyone help?

The range of f(x)=(2x+2)/(x-1) |
2015-11-25 |

From Nazrul:
f : R to R is a function which is defined by f(x)=(2x+2)/(x-1).
Is f(x) an onto function? Please explain.
What is the range of this function?
Thank you very much for your previous help.

From Karel Marek:
Math Is Book 6 (Ebos/Tuck) question 5(b) gives a surprising answer at the back of the book..The question is:
Indicate the domain and range for this: y = sqr(x-9) (Square root of) The answer for the domain is x>=9 which is not surprisingly, but the range is y>=0, yER ... which I could understand if you were not allowed to transform the equation into x as the subject.. But all example on the facing page DO TRANSFORM the equation at will with x and/or y as the subject.. Can you explain this...
