Final answer:
The information can be expressed in terms of the function g as g(a) = 50 cubic yards.
Step-by-step explanation:
To express the information in terms of the function g, we need to find the relationship between the area of the garden and the cubic yards of dirt needed.
From the given information, we know that a garden with an area of 5000 ft2 requires 50 cubic yards of dirt. Therefore, the equation is:
D = g(a) = 50 cubic yards
Solving for a, we have:
a = 5000 ft2
So, the information expressed in terms of the function g is: g(a) = 50 cubic yards.
