A student has a cup containing coffee. He observes the color of the coffee. He weighs the cup containing coffee. He then adds 25 g of sugar to the coffee. The table shows the student's results. TABLE
Substance Weight (g) Color Coffee and cup 335 Dark brown
25 White Sugar
Coffee and cup after sugar is added 360 Dark brown
The student concludes that the sugar added to the coffee still exists.

What evidence best supports this conclusion?

A. The sugar welghs 25 g.
B. The color of the sugar is white.
C. The coffee and cup after the sugar is added is 360 g.
D. The color of the coffee after the sugar is added Is dark brown.

D. The color of the coffee after the sugar is added Is dark brown.

Explanation:

It says that the student concludes that the sugar added to the coffee still exists like my dad who always is making himself some coffee I know that when you add sugar to the coffee it turns dark brown.

a and c

c is 100% but i am confused in a

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 .
