In this problem the surface area of the composite figure is equal to the area of the base of the rectangular prism plus the lateral area of the rectangular prism, plus the area of the two triangular faces of triangular prism, plus the area of two rectangular faces of the triangular prism. we know that
The horizontal asymptote of the function is the minimum number of deer in the area.
The equation is given as:
Expand the numerator
Cancel out the common factor
Hence, the equation of horizontal asymptote is:
The horizontal asymptote means that, the number of deer will never be less than 40
