Determine if a question is asking for the positive zero ( root ) coordinate, the vertex x coordinate or the vertex y coordinate. 1. How long until the ball is at its highest point?

2. How long is the ball in the air?

3. When will the ball hit the ground?

4. How high did the ball get?

5. When will the ball be at its highest point?

6. How high is the ball at its highest point?

​

on a coordinate grid, point a is at (−4.0, −2.4) and point b is at (4.0, −2.4). point b is a reflection of point a across the –axis. input either a lowercase x or i think is the right awnser

step-by-step explanation:

sample answer: you can determine whether each element of the domain is paired with exactly one element of the range. for example, if given a graph, you could use the vertical line test; if a vertical line intersects the graph more than once, then the relation that the graph represents is not a function.
