Calculus 1?
To find concavity you must take the second derivative.
As you would to find your local maximums and minimums (critical points) in the first derivative by setting y' = 0, to find points of inflection you set acceleration, y" = 0.
Now that you know where the point in which the function is neither concave up or concave down (at the points of inflection) plug x-values between them into the second derivative for x. If y" is positive between those particular points will be concave up and if y" is negative it will be concave down between that interval.
For a better understanding you might find a good video on Youtube explaining this if you search "Points of Inflections" or "Concavity of a function".
Cheers.
Answer:
Step-by-step explanation:
An animal rescue group saved 50 baby birds and 44 adult birds during the month of August. Ratio of baby birds saved to adult bird saves is expressed as number of baby birds saved divided by number of adult birds saved. So the ratio of baby birds saved to adult birds saved for august becomes
50/44 = 25/22
the ratio of baby birds saved to adult birds saved for September becomes
36/30 = 6/5
6/5 is the biggest ratio, hence , the ratio of baby birds saved to adult birds saved is higher in September.
Answer:
The answer is 0 because if it was negative, there are no solutions and if the discriminant is equal to zero we have a solution.
Answer:
x=44
Step-by-step explanation:
since m, which I'll assume is the gradient, is undefined, the line is a vertical line. Since it passes through the point (44, 7), the equation of the line is x=44
This is the theorem for you
