<span>Inflection points are where the function changes concavity. Since concave up corresponds to a positive second derivative and concave down corresponds to a negative second derivative, then when the function changes from concave up to concave down (or vise versa) the second derivative must equal zero at that point. So the second derivative must equal zero to be an inflection point. But don't get excited yet. You have to make sure that the concavity actually changes at that point.</span>
the answer is 9304=9 thousands 3 hundreds 4 ones
6(3x+5)
6*3x=18x
6*5=30
<u>18x+30</u> is your answer! I hope this helped! :)
Answer:
the answer is 2.1
Step-by-step explanation:
using a calculator:
1. type in 4.2
2. multiply 4.2 by 1/2
3. the answer will then be shown as 2.1
The first answer is 40 second 65 third 56 and then fourth 90
