9 (x-18)=3x-18
9x-9.18=3x-18
9x-3x=9.18-18
6x=8.18
x=8.3
x= 24
Yes: example-because if u are running u are using energy
Given:

To find:
The correct function.
Explanation:
Let us consider the function given in option D.

Differentiating with respect to x we get,

Substituting x = 2 in the function f(x), we get

Therefore, the given conditions are satisfied.
So, the function is,

Final answer: Option D
I believe this is a rotation through an angle of +90°, anticlockwise, (counterclockwise), with the center of rotation origin(0,0)
To describe rotation we give the center of rotation and the rotation angle in degrees stating whether it is clockwise or counterclockwise.
