20 POINTS! Please help I need help with 22 and 21
21. Which letter represents where the marble has
the greatest kinetic energy? A, B,C or D.
22. If you neglect friction. The gravitational
potential energy of the marble at the start is
the kinetic energy of the marble at the
end.
a.
greater than
b. less than
c. equal to

asthenosphere and convection

true is the correct answer

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 .
