Question

What is the directrix of the parabola? (y+4)2=4(x−2)

Answer 1

Answer:

the answer is 1

Step-by-step explanation:

Answer 2

Answer:

x=1

Step-by-step explanation:

for y²=4ax

directrix is x=-a

for y²=4x ,directrix is x=-1

for y²=4(x-2), shift directrix 2 units right.

so directrix is x=-1+2=1

so for (y+4)²=4(x-2) directrix is x=1
