Answer:
A) Not a function
B) Function
C) Function
D) Not a function
Step-by-step explanation:
If the relation has two of the same x-values (that equal different y-values), it is not a function. In other words, if each input value leads to only one output value, classify the relation as a function.
{<u>(-4,3)</u>, (-2,-1), <u>(-4,8)</u>} = Not a function
{-4, 3), (-2.-1), (-7, 8)} = Function
{-4,-2,-7, 7}
= Function (I think?)
{-4,3). <u>(-2, -1)</u>. <u>(-2, -8)</u>, (-7,8)}= Not a function
