Sorry i don’t know the answer maybe some one else knows
2+3=5
25/5=5
5x2=10 3x5=15
so the answer is:
£10:£15
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.
Answer:
14
Step-by-step explanation:
Range is, basically, the span of all y-values.
To find range, you take the highest y-value and subtract from it the lowest y-value.
Here the highest "y" is 7 and the lowest is -7, so the range is 14.
