Question 106766: I need to find x and y ranges for the following problems and then graph accordingly. I need very detailed information and step by step help, if you can. I need to understand this. THANK YOU!!!
1. f(y)=-5y+3 2. f(x)=x^2-2x+1

You can put this solution on YOUR website! find x and y ranges for the following problems and then graph accordingly. I need very detailed information and step by step help, if you can. I need to understand this. THANK YOU!!!
1. f(x)=-5x+3
----------------
I changed your y's to x's because I don't know what you mean by f(y).
Domain: all Real Numbers because there is nothing in the equation
that would prevent x from having a particular value
----------
Range: all Real Numbers for the same reason
------------
2. f(x)=x^2-2x+1
f(x)= (x-1)^2
Vertex is at (1,0) the the parabola opens up.
Domain: all Real Numbers for the reason given above
Range: All Real numbers that are greater than of equal to zero
because the parabola goes up from (1,0)
