Question

A company has two packaging machines in a unit, each with a different daily capacity. The capacity of machine one is defined by the function f(m)=(m+4)^2+100, in the capacity of machine two is defined by the function g(m)= (m+12)^2-50, where M is the number of minutes the packaging machine operates. Create the function C(m) that represents the combined capacity of the two machines.
