Question 68677
To find the point of intersection, we can graph the function.

{{{graph (200, 200, -5, 4, -5, 4, x+2, (-x)-4)}}}

<br> Looking at the graph, the point of intersection is (-1, -3),x=-1 and y=-3

<br>f(x) = g(x), f(x)=x+2 and g(x)=-x-4
-x - 4 = x + 2
-2x = 6
x = -3
<br>
f(x) = x + 2 , x = -3
f(x) = -3 + 2
f(x) = -1

<br> or
g(x) = -x-4, x = -3
g(x) =-(-3) - 4
g(x) = 3-4
    = -1
