1. Consider the pyramid ABCDE in the figure 1 attached:
Each side of the square base equals

(units)
Area of 1 lateral side of pyramid ABCDE is

so the total lateral area is

(units squared)
and the total surface area is

(units squared)
2. Now consider the second figure KLMNP, Sydney's pyramid:
The lateral area is

so the total area of the second pyramid is

So 2 things can be said about the areas:
i) the lateral area of Sydney's pyramid is

times larger than the lateral area of the original pyramid.
ii) The total area of Sydney's pyramid is

units squared larger than the total area of the original pyramid.
As the line raises from left to right, the slope must be positive, so only the function, f(x)=x-3, has a slope greater than zero. Additionally, at x=0, the y-value is at, or around, -3, confirming that f(x)=x-3 is the correct solution.
