These four forces and their directions are indicated below. If the thrust acting on an airplane is greater than the drag, then
A.
the airplane will accelerate backward.
B.
the weight will be greater than the lift.
C.
the airplane will accelerate forward.
D.
the lift will be greater then the weight.

i think it would be 5

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 .
