Understanding Mason's Ladder Problem

The video tutorial explains a problem involving Mason on a ladder with 15 steps, each 0.5 meters apart. It introduces the function h(n) to denote Mason's height above the ground after moving n steps. The tutorial discusses the domain of this function, emphasizing that it consists of integer values only, as Mason cannot move fractional steps. The domain is defined as a subset of integers ranging from -5 to 10, representing the possible steps Mason can take up or down the ladder.

What is the total number of steps on the ladder Mason is standing on?

• 10

• 12

• 15

• 20
