Answer:
Function A.
Step-by-step explanation:
In function A, as the x-values increase, the y-values triple. This will continue to grow by a larger and larger amount for every increase in x.
In function B, as the x-values increase, the y-values go up by 100. This is a constant rate of change; the function will never change by more than 100.
In function C, as the x-values increase, the y-values go up by 10. This is a constant rate of change; the function will never change by more than 10.
In function D, as the x-values increase, the y-values go up by 2. This is a constant rate of change; the function will never change by more than 2.
Since function A grows by larger and larger amounts every time, it will have the greatest values of y for very large values of x.
