If she can only work 15 hours a week and earns $7 per hour, just multiply 7 by 15 and you'll have your answer :)
Answer: Not a function
<u>Step-by-step explanation:</u>
The graph fails the vertical line test. In other words, when you draw a vertical line anywhere through the curve, the line passes through two points.
Bonus: If you do not have a graph, it is not a function if there is one x-value that has two different y-values.
For example, If (1, 2) and (1, -2) lie on the curve, then it is NOT a function because the x-value (1) has two different y-values (2 & -2).
The correct answer is vertex.
Vertex is minimum(lowest) point when parabola opens upwards, it is the maximum(highest) point when parabola opens downward, it is the farthest point on left if parabola opens right and farthest point towards right if parabola opens left.
So the correct answer to this question is option D
1,2,7,14 would be your answer :)
