A.
quadratic binomial
B.
quadratic monomial
C.
linear binomial
D.
quadratic trinomial

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value

x = -4

step-by-step explanation:

- 20 - 4(x + 3) = 4x

=> -20 - 4x - 12 = 4x

=> - 32 -4x = 4x

=> -32 = 4x + 4x

=> - 32 = 8x

=> -32/8 = x

=> -4 = x
