A 10g ice cube, initially at 0 C, is melted in 100g of water that was initially 20 C. After the ice has melted, the equilibrium temperature is 10.93 C a. The total heat lost by the water (the specific heat for water is 4.186J/g/K

true

explanation:

does anyone know or what?

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 .
