At what point is the vertex? Is it a minimum or maximum?
(-2,7);maximum
(-1,0);minimum
(2,-9);minimum
(0,-5);minimum
(2,-9);maximum
(4,-5);maximum

(2, -9); minimum

Step-by-step explanation:

The vertex is the point that either has the largest y value (maximum) or it has the smallest y value (minimum). It is also the point on the graph where if it's a maximum, all the points to the left and right of it are less than it and if it's a minimum, all the points to the left and right of it are more than it.

Looking at the table, we see that the smallest y value is -9. The values beside it are -5 and -8, where are both greater than -9. So, this is a very potential candidate for minimum.

The largest y value is 7. We can't see all the values beside it, but we can guess from the trend, that the y values on one side will be more. So, it can't be a maximum.

Thus, the vertex is at the minimum (2, -9).

Hope this helps!

(2,-9);minimum

Step-by-step explanation:

Since the data is symmetrical about x = 2,

Vertex is (2, -9)

On both sides of x = 2, the y values are greater than -9. Therefore it's a minimum point

the red lines denote the population of the bacteria after 35 hours. that would be 2,409.24. the y-intercept is the blue line which is 800 because that is the starting point. the equation used to make the graph is 800(1.032)^h, where h is the number of hours.

step-by-step explanation:

1/800 is the right answer
