Answer:
No, the graph does not represent a function because it does not pass the vertical line test.
<h2>What is a function?</h2>A function is when each x-value only has one y-value. We know that a graph represents a function if it passes the vertical line test.
<h3>Vertical Line Test</h3>To pass the test, any vertical line that we draw on the graph should only touch one point.
A vertical line is a straight line that goes from top to bottom.
- Draw vertical lines through points on the graph, like in the photo below.
- Check if any vertical lines touch more than one point.
The yellow vertical line touches two points, which is more than one. So, the graph does not pass the test. This graph is does not represent a function.
Chech the picture below.
if the person kicked it from the ground, that means its initial height is 0.
it reaches its maximum height at the y-coordinate of its vertex, and it will hit the ground when y = 0, as you see in the picture.
now let's find the y-coordinate of its vertex
when will it hit the ground?
