Answer: Yes, it is a function</h3>
This is a function because there are no x values that repeat.
If we had repeated x values, then this would mean a certain input x leads to multiple outputs y, and that would not make it a function.
For instance, if we had (2,1) and (2,2) at the same time, then the input x = 2 leads to multiple outputs y = 1 and y = 2 at the same time. A function would not be possible in this example.
A function is only possible if any input x leads to exactly one output y. It is possible for y to repeat itself and still have a function.
Answer:
£2.00
Step-by-step explanation:
Badly worded, as they oftena are! But to me it means
30% spent
60% saved (I.e also taken away and put somewhere else)
10% leftover equals 20p
So 20p equals 10% of what she originally had, so 100% must be £2.00, does that make sense?
