Final answer:
To find the total cups of coffee made by Kate and Stella, you need to add up their individual functions f(x) and g(x). The function that represents the total cups of coffee made today is h(x) = 10 + 15 = 25.
Step-by-step explanation:
To find the total cups of coffee made by Kate and Stella, you need to add up their individual functions f(x) and g(x). Let's assume Kate made 10 cups of coffee (f(x) = 10) and Stella made 15 cups of coffee (g(x) = 15). To represent the total cups of coffee they made today, you can add their functions together: h(x) = f(x) + g(x). Therefore, the function that represents the total cups of coffee made today is h(x) = 10 + 15 = 25.
