The surface area of a cone is determined by the equation
SA - #18+er, where is the radius and s is the slant height. The
functions f(x) and g(x) both model the surface area of a cone.
One of the functions represents the surface area of a cone with a
radius of sand a slant height of x. The other function represents
the surface area of a cone with a slant height of sand a radius of x
Which statement correctly matches the description of the
function with the domain of the function in the context of the
problem situation?
The function f(x) models the surface area of a cone with a
radius of 5, a slant height of x, and has a domain in the context
situation of x<5.
The function f(x) models the surface area of a cone with a
radius of 5, a slant height of x, and has a domain in the context
situation of x>5.
© The function g(x) models the surface area of a cone with a
radius of 5, a slant height of x, and has a domain in the context
situation of x<5.
The function g(x) models the surface area of a cone with a
radius of 5, a slant height of x, and has a domain in the context
situation of x>5.
