Write the equation for a parabola with the vertex at (–1, 3) and the equation of the directrix y = 1. (x – 1)^2 = (y + 3)

(x + 1)^2 = 8(y – 3)

(x – 1)^2 = 8(y + 3)

(y – 3)^2 = 2(x + 1)

answer is (x+1)^2=8(y-3)

the correct answer is 5 6 and 7

x = 17

step-by-step explanation:

1st step: isolate x.

24 - 3x = -27

-24         -24

-3x   =   -51

2nd step: divide.

-3x     =   -51

  3             3

  x       =     17

hope this

step-by-step explanation:

we have

using a graphing tool

see the attached figure

this is a quadratic equation (vertical parabola) open up

the vertex is a > vertex

the domain of the function is all real > interval (-∞,∞)

the range of the function is the > [-6.125,∞)

the function has two x->   and

the function is increasing over the > (0.25,∞)

the function is decreasing over the > (-∞,0.25)
