Write an equation of the parabola in vertex form that passes through (13,8) and has vertex (3,2).

Step-by-step explanation:

Vertex: (3,2)

Point: (13,8)

The equation form is

h = 3

k = 2

y = 8

x = 13

Plug in the values into the form..

Simplify and solve for a..

Plug a into the equation..

Hope this helped you!

answer: idk

step-by-step explanation:

let's call the solutions x₁ = (5 - 2√7)/3 and x₂ = (5 + 2√7)/3

then the equation is (x-x₁)(x-x₂) = 0

if you fill that in you get a lot of numbers which you can recognize as ax²+bx+c=0.

step-by-step explanation:

you can see that a=1 (there is just an x²)

b = (-5 -2√7 + 2√7 - 5)/3 = -10/3

c = -2√7)/3 ) * (-5+2√7)/3) = -1/3

so your answer is 3x^2 – 10x – 1 = 0
