On the graph shown, what is f (-2)? the first part of the graph is continuing to the left from the point negative two comma negative one exclusively. the second line segment joints the point negative two comma one inclusively and two comma one exclusively. the last part of the graph is continuing to the right from the point positive two comma positive three.

25% is the answer

(0.2)+(-8)=0.3+-3+0.3m is the equation i guess? ?

step-by-step explanation:

answer: 3.26019516

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
