A) degree = 3 & L. C. = 3
B) degree = 4 & L. C. = 9
C) degree = 4 & L. C. = 3
D) degree = 2 & L. C. = 3

hello from mrbilldoesmath!

answer:

the domain is the set { -2, 0, 2, 3}

discussion:

the domain is the set of x values in the ordered pairs (x,y). taking the x, or first component, of each ordered pair gives   -2, 0, 2, 3.

you,
