The point of inflection is calculated by equating the second derivative to zero and determining x from there.
f"(x) = -x²2xsinx² + cosx²(2x) = 0
2xcosx² - 2x³sinx² = 0
2x (cosx² - xsinx²) = 0
2x = 0 ⇒ x = 0
cosx² - xsinx² = 0 ⇒ x = 3.82 (if you use shift+solve in your scientific calculator)
Thus, the function only has 1 point of inflection and it is at x = 0.
3:4 = 3/4
3/4 = 3 divided by 4
3 divided by 4 = 0.75
0.75 = 75%
C. 75%

idk i'm probably wrong
199/100 = 1.99
1.99*20 = 39.8
20% = 39.8
