Solution

To determine which function grows the least, we need to understand the general behavior of each function.

A. ๐‘”(๐‘ก)=3๐‘ก^2โˆ’๐‘ก: This is a quadratic function. It grows faster as t increases.

B. ๐‘(๐‘ก)=๐‘ก^2โˆ’5๐‘ก: This is also a quadratic function. It grows faster as t increases.

C. ๐‘’(๐‘ก)=๐‘’: This is a constant function. It does not grow at all as t changes.

D. ๐‘Ž(๐‘ก)=๐‘ก^5/2: This is a power function. It grows very fast as t increases.

E. ๐‘–(๐‘ก)=ln(๐‘ก/100): This is a logarithmic function. It grows slowly as t increases.

Comparing these functions, the function that grows the least is the constant function ๐‘’(๐‘ก)=๐‘’.
