{(–1, 1), (–2, 1), (–2, 2), (0, 2)}
In a function, each input has an output
Each domain has a range. In a function, range can be repeated but domain cannot be repeated. Same domain cannot have two range values.
Here domain is {-1, -2, -2, 0}
Range is { 1, 1, 2, 2}
Domain -2 is repeating so this relation is not a function
Answer : No; a domain value has two range values.
Answer:
5
Step-by-step explanation:
0
Plug in the corresponding numbers to the corresponding variables. Note that:
y = 9
z = 0
Plug in 9 for y, 0 for z.
(2z)/y = (2(0)/(9) = (0)/9 = 0
0 is your answer.

450 pennies
2/3 ➡ 3/3 × 2/3 = 6/9
let's call it 9x
the bank contains 6x after she removes 100 pennies 4x is left
which means 2x = 100 pennies and x = 50 pennies
therefore the bank can carry 50 × 9 = 450 pennies
