1. all functions are relations.
2.
-7 + 3(-12) ÷ (-3)
-7 - 36 ÷ -3
-7 - (-12)
-7 + 12
5
3.
f(n) = n² - n f(-4)
f(-4) = -4² - (-4)
f(-4) = 16 - (-4)
f(-4) = 16 + 4
f(-4) = 20
hope this helped, God bless!

Answer:
Option D. x = 4
Step-by-step explanation:
we have
we know that
The solution of the system
f(x)=g(x)
is the x-coordinate of the intersection point both graphs
using a graphing tool
The intersection point is (4,2)
see the attached figure
therefore
The solution is x=4
