Answer:

The vertical line test can be used to determine whether a graph represents a function. A vertical line includes all points with a particular x value. The y value of a point where a vertical line intersects a graph represents an output for that input x value.

Answer:

The answer is d

Step-by-step explanation:

I graphed it

-b/2a to get the vertex

3x^2-12+9

-(-12)/(2)(3)=2

plug in 2 to the function

12-24+9=-3 which is the y value on the graph

(2,-3) is the vertex

Answer:

The second table.

Step-by-step explanation:

In the first table, the speed goes from 45 down to 43; then down to 41; then up to 42; then up to 43.  It decreases and then increases.  This is not the correct table.

In the second table, the speed goes from 45 up to 47; then up to 49; then down to 48; then down to 47.  It increases and then decreases; this is the correct table.

To verify, we check the last two tables.  The third table stays at 45, then decreases to 43 and 41.  This is not correct.

The last table decreases from 45 to 43, then decreases to 41, then stays constant.  This is not correct.

The second table is the only correct one.

The intersection of 2 lines is a point so A. Because that’s where the lines meet then if they keep going they shouldn’t touch again.
