It is awesome. Love it, it helps me work on my algebra homework, it great for checking my work, and it does everything that we learn, but damn the app is great again, my favorite feature is the camera, it has got me through some tricky assignments but has also really helped me understand math better.

William Racette

f (-2) = -16 + 12 + 24. f (-2) = 20. f' (x) changes from negative to positive when it passes through x = -2, so it has local maximum at x = 1. Local minimum at x = 1 : f (1) = 2 (1) 3 + 3 (1) 2 −12 (1) f

Maximum and Minimum

The second derivative is y'' = 30x + 4. At x = −3/5: y'' = 30 (−3/5) + 4 = −14. it is less than 0, so −3/5 is a local maximum. At x = +1/3: y'' = 30 (+1/3) + 4 = +14. it is greater than 0, so +1/3 is a local
