How many peanut butter cups does Benny have if he has 2 times as many as Karen. Karen has 80 peanut butter cups.

160

Explanation:

if benny has 2x more than karen and karen has 80 you would multiply 80 by 2 to get 160. therefore benny has 160. hope that helps

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 .
