I believe the answer to question 2 is the first option, and the answer to question 3 is the last option
A relation can be a function if an x value is not paired with more than y-values.
The x and y values are flipped when finding an inverse.
So, if in the inverse function a y value is paired with more than one x values, this will mean that in the function an x-value was paired with more than one y-values.
Looking at the graph we can say that no y-value in the inverse is paired with more than one x values, so the original relation would be a function.
So the answer is TRUE
Answer:
A
Step-by-step explanation:
It would be B if it was asking the ratio of non-mammals to mammals.
The answer is 27 (54 divided by 2 equals 27; 27 is equal to 27 and adds up to 54 when combined with another 27)
