Answer:
We can find if a critical point is a local minimum or maximum by looking at the second derivatives.
Step-by-step explanation:
If you take the first derivative, you will find the slope at the given point, which if it is a minimum or a maximum will be 0.
Then we take the second derivative. If that number is a positive number, then we have a local minimum. If it is a negative number, then it is a local maximum.
If we divide 12.6/4.5 by 3 we receive 4.2/1.5. So yes they are proportional. <span />
This will be -7 because this would make the denominator b + 7 = 0.
Answer: #2
Step-by-step explanation:
cuz i said so
It is option D because we can’t divide by zero and x - 2 = 0 when x = 2
