Water is being poured into a "Dixie cup" (a standard cup that is smaller at the bottom
than at the top). The height of the water in the cup is a function of the volume of
water in the cup. The graph of this function is
(a) increasing and concave up
(b) increasing and concave down
(c) a straight line with positive slope.

(c) a straight line with positive slope.

Step-by-step explanation:

Functions

We are required to find a function that relates the height of the water in a cup to the volume of water in the cup.

The cup has a shape of a cone open upwards. The volume of a cone of height h and radius r is

This function relates the height with the volume, to find the required function, let's solve for h

Rearranging

Being all the values positive, the height and the volume are linearly related with positive slope

(c) a straight line with positive slope.
