Final answer:
The function that will have y-values for very large values of x is option C. y = eˣ, which represents exponential growth.
Step-by-step explanation:
The function that will have y-values for very large values of x is option C. y = eˣ, which represents exponential growth. The function y = eˣ is an exponential function where the base e is a constant approximately equal to 2.71828.
As x increases, the value of eˣ increases exponentially, resulting in very large y-values.
