Domain & Range of Quadratic Functions

What are the domain and range of 

 $g\left(x\right)=-\frac{1}{4}\left(x-17\right)^2\ +\ 61?$  

• Domain: All real numbers
  Range:  $g\left(x\right)\le61$  

• Domain:  $x\le17$  
  Range:  $g\left(x\right)\le61$  

• Domain: All real numbers
  Range:  $x\le17$  

• Domain:  $g\left(x\right)\ge61$  
  Range:  $x\le17$  

Write the following function to vertex form and give its domain and range (in words).

 $y\ =\ -x^2-2x+3$  

Which graph represents the following:

 $y\ =\ -\left(x-2\right)^2+2$   $1\le x\le3,\ 1\le y\le2$
