A student has measured the force output from using a lever at various effort distances and input forces. The distance over which the load travels was held constant.  The student varied the input force and the distance by which the force was applied and plotted the points using a bar graph. The student did not label the data plotted in the bar graph. Using your knowledge of mechanical advantage, which data correspond with the input force and which data correspond with the output force?

A.
The darker bars are the input force, the lighter bars are the output force.

B.
The lighter bars are the input force, the darker bars are the output force.

explanation: magnetic pole, region at each end of a magnet where the external magnetic field is strongest. the south-seeking pole, or any pole similar to it, is called a south magnetic pole. unlike poles of different magnets attract each other; like poles repel each other.

we have been given a quadratic function and we need to restrict the domain such that it becomes a one to one function.

we know that vertex of this quadratic function occurs at (5,2).

further, we know that range of this function is .

if we restrict the domain of this function to either or , it will become one to one function.

let us know find its inverse.

upon interchanging x and y, we get:

let us now solve this function for y.

hence, the inverse function would be if we restrict the domain of original function to and the inverse function would be if we restrict the domain to .
