    The   equation   of  the   directrix   of\[{{(x-1)}^{2}}=2(y-2)\]is:

    A)  \[2y+3=0\]        

    B) \[2x+1=0\]

    C)  \[2x-1=0\]      

    D)        \[2y-1=0\]

    E)  \[2y-3=0\]

    Correct Answer: E

    Solution :

    Equation of directrix of\[{{(x-1)}^{2}}=(2y-2)\]is \[y-2=-\frac{1}{2}\] \[\Rightarrow \]               \[2y-3=0\]
