Hello!
In a function, each input must have only one output. Outputs can have multiple inputs, but each input must have one output. For example, {(4,-1), (4,-2)<span>} is not a function, as 4 has two outputs.
In B, -2 has two outputs, 3 and 1, so it is not the answer.
In C, 3 has two outputs, 5 and 2, so it is not a function.
In D,-1 has two outputs, 1 and 5, so it will not work.
In A, each number has one output, so it is a function.
I hope this helps!</span>
Answer:
y=3/2x-7
Step-by-step explanation:
In order to find the amount left after both sisters ate the cereal, we have to add the amount of cereal the two sisters ate.
Katrina ate 1 3/4 and her sister ate 7/8.
(1 3/4 + 7/8)
(you put a parentheses around it so that you add the two first before subtracting it from the original amount)
Then, we would subtract it from the original amount: 12 1/2.
-> The equation would be: 12 1/2 - (1 3/4 - 7/8).
