Unit 1 Assessment - 2020 The graph of y = |x+4| - 8 is reflected across the y-axis. What is an equation of the reflected graph?
A. y = |4 - x| - 8
B. y = |x - 4|+ 8
o C. y = |4- x| + 8
o
D. y = - |4 - x|- 8

hi! i think the answer is 1/2 : )

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
