Select Is a Function or Is not a Function to correctly classify each relation. {(2, 2),(4, 4),(6, 6),(8, 8)} is this function or not function
{(0, 3),(3, 5),(5, 6),(8, 4)} is this function or not function
{(1, 2),(3, 3),(4, 8),(6, 3)} is this function or not function
{(3, 4),(5, 2),(5, 6),(7, 3)} is this function or not function
Please help me I will give you the brain thing and extra points.

all of these but the last one are functions, and the last one is not because there are repetitive (x) factors.

can you rephrase the question ? it is unclear : -)

step-by-step explanation:

the data of the detroit pistons in numerical order from least to greatest is 0.30, 0.37, 0.55, 0.62, 0.69, 0.72, 0.73, 0.75, 0.77, 0.78, 0.80, 0.81, 0.81, 0.83, 0.84, 0.89

the data of the miami heat in numerical order from least to greatest is 0.50, 0.50, 0.56, 0.57, 0.67, 0.72, 0.72, 0.72, 0.75, 0.75, 0.76, 0.81, 0.82, 0.90, 1.00, 1.00

the detroit pistons median : 1.52

the miami heat median: 1.47

the iqr of this data is 0.05
