So, for the second problem, they've reversed the situation: Now we have the temperature, and we have to think backwards to figure out the number of cricket chirps (in five minutes)!

We ended up with 60 degrees (somehow). Well, let's subtract 37. That gives us 23. What does this number mean? It is the number of times the cricket chirps in 15 seconds. But we want five minutes... I bet you can take it from here... :)

1. How can you tell that a point on the graph is a maximum or minimum?
spin [16.1K]

Answer:

1) To see whether it is a maximum or a minimum, in this case we can simply look at the graph. f(x) is a parabola, and we can see that the turning point is a minimum. By finding the value of x where the derivative is 0, then, we have discovered that the vertex of the parabola is at (3, −4).
