Answer:
It is 6. The student who got a two did not use order of operations.
Step-by-step explanation:
PEMDAS
You must do division before subtraction. 4/2 = 2.
8 - 2 = 6
Answer:
First and Second Derivative Tests. First identifies critical points. The second determines behavior around the point.
- Concave up is a minimum
- Concave down is a maximum
Step-by-step explanation:
The extreme points of a function are called the maximum and/or minimums. AT these points, the function (or y-values) are at their highest or lowest. These points are often the peaks and valleys of a function on a graph. You can determine if a function has max or min using the first and second derivative tests. The first determines critical points of the function. The second determines behavior around a point. If the value is positive then the function is concave up. It forms a valley and the point is a minimum. If the value is negative then the function is concave down. It forms a peak which has a maximum.
