Let

a)
Find
b)
Find the domain of
denominator cannot be equal to zero, so exclude value of which makes it equal to zero
=>
so, the domain: { elememt :
c)
Find the range of
-> it's upward parabola,has minimum ;so, write it in vertex form

=> vertex (minimum) is at (,)
so, the range is :
{ element : }
