Which of the graphs below correctly solves for x in the equation −x2 − 3x − 1 = −x − 4?

Answered by maham237 @



We have
−x² − 3x − 1 = −x − 4

let
f(x)=
−x² − 3x − 1
g(x)= −x − 4
the solution for
f(x)=g(x) is the intersection both graphs

using a graph tool
see the attached figure

the solution are the points
(-3,-1)
and
(1,-5)
