A small rock moves in water, and the force exerted on it by the water is given by equation f=kv. The terminal speed of the rock is measured and found to be 2.2 m/s . The rock is projected upward at an initial speed of 6.5 m/s . You can ignore the buoyancy force on the rock. Part A In the absence of fluid resistance, how high will the rock rise? Express your answer using two significant figures.

good looking response

which statement about this sum is true? −245+2.7

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 .
