Test will give medal to best 1 when the air under the envelope is heated, the balloon lifts. which of the following statements is true. a. hot air balloons use radiation to rise b. hot air balloons use conduction to rise c. hot air balloons use convection to rise d. hot air balloons use air resistance to rise is the answer answer c? ,

this is a good question! i'll do some research and come back when i have the 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 .
