The Relation between the height of the plant (y in cm) with respect to exposure to sunlight is governed by following equation \[y=4x-\frac{1}{2}{{x}^{2}}\] where x is the number of days exposed to sunlight. |
A) \[4x-\frac{1}{2}{{x}^{2}}\]
B) \[4\text{ }-\text{ }x\]
C) \[\text{x }-\text{ 4}\]
D) \[x-\frac{1}{2}{{x}^{2}}\]
Correct Answer: B
Solution :
\[y=4x-{{x}^{2}}\] \[\frac{dy}{dx}=4-\frac{1}{2}\times 2x=4-x.\]You need to login to perform this action.
