Final answer:
To determine the function that has the least minimum value, you need to compare the given functions f, g, h, and k and analyze their graphs or evaluate the minimum values of their equations.
Step-by-step explanation:
The function that has the least minimum value can be determined by analyzing the graphs or equations of the given functions. By comparing the y-values of the graphs or evaluating the minimum values of the equations, we can find the function with the smallest minimum value.
For example, if the graph of function f is located below the graphs of the other functions at the lowest point, then function f would have the least minimum value.
Therefore, to determine the function that has the least minimum value, you need to compare the given functions f, g, h, and k and analyze their graphs or evaluate the minimum values of their equations.
