What is the the vertex of the parabola (y−1)2=24(x+2) ?
(-2,1)
(2,-1)
(2,1)
(1-2)
1 answer:
Answer:
The vertex is (-2,1)
Step-by-step explanation:
The standard equation for the parabola is 4p(x-h)=(y-k)^2
Rewrite (y-1)^2=24(x+2) in standard form
4*6(x-(-2))=(y-1)^2
Therefore parabola properites are:
(h,k)=(-2,1)

Regroup terms
2(x + 2) = 1
Divided both sides by 2
x + 2 = 1/2
Subtract 2 from both sides
x = 1/2 - 2
Simplify 1/2 - 2 to -3/2
<u>x = -3/2</u>
