Answer:
C is a function... all the others are not functions since it doesn't pass the line test.
Step-by-step explanation:
-10 and -2
Because -10-2= -12 and -10 x -2 = 20
Hope this helps :)
Answer:
A.4
Step-by-step explanation:
Because 4/12 is simplified to 1/3 and 2/4 would be simplified to 1/2. 1/2 > 1/4
Easily we can use formula y=(x-h)^2 +k
as equation of a parabola if vertex was (h,k):
Y=(x-1)^2 + 3
and maybe node (2,6) is incorrect for this vertex of a parabola!!!
D because those options do not intersect and are part of the universal set
