Here, The function: y = -x² + 4
Input values would be x coordinates & output values would be y.
When, x = 1, y = (-1)² + 4 = 1 + 4 = 5
x = 2, y = (-2)² + 4 = 4 + 4 = 8
x = 3, y = (-3)² + 4 = 9 + 4 = 13
In short, Your Three input values are: 1, 2, 3
Three Output values are: 5, 8, 13
Hope this helps!
Answer: It will take the boat 0.11 hour to cross the river
From the original starting point, the boat end up 1.85 miles away from that point.

Answer:
The first one.
Step-by-step explanation:
For something to be considered to be a graph, every x value must have 1 y value. It does not matter if y values are the same, but you MUST make sure there is ONLY ONE of each value. So for example the second one wouldn't be a function because -5 appears twice for the x values, but with different y values. This would mean when graphed, it would fail the vertical line test (if you put a vertical line anywhere on the graph you will only get one point).
Add 7 to both sides : -6 = v
no. he isn't correct because the scale factor is an improper fraction. 2/5 means you have 2 out of 5, but if you have 8 out of 3, that means you have 2 3s and 2 more leftover. it wouldn't be a reduction, it'd be increasing!
