Y is less than or equal to -16 i think but I’m not sure
The awnser is one I hope I helped you with this question
Since .7 is above 5.
$45.71 would turn to $46.00.
You would round 45... the 5 to 6...
To be $46
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.
