Answer:
5/4 8.10.............0.0 5=7=9
I think you meant the two <em>segments</em><em> </em>are identical, if so then:

(f+g)(x)=0
f (x) + g (x)=0
now,
substitute their values
x^2 -4x + x -18 = 0
x^2 -3x -18 =0
x^2 - 6x + 3x - 18 =0
x (x-6) + 3 (x-6) = 0
(x-6)(x+3) = 0
we have to find it's zeroes (or roots) now:
x-6 =0
x = 6
x +3 =0
x = -3
Answer:
I think it's C
Step-by-step explanation:
A is go up one time
B is go down one time
C is... not sure what's going on there
