[Answer] Which expression is equivalent to (f+g)(4)?

Answer: A. f(4)+g(4)
Which expression is equivalent to (f+g)(4)?

At terminal (or settling) velocity the excess force F g due to the difference between the weight and buoyancy of the sphere (both caused by gravity) is given by: F g = ( ρ p − ρ f ) g 4 3 π R 3 {\displaystyle F_{g}=\left(\rho _{p}-\rho _{f}\right)\ g\ {\frac {4}{3}}\pi \ R^{3} }

For the operations involving function f and assuming the height of f is 1.0 the value of the result at 5 different points is indicated by the shaded area below each point. Also the vertical symmetry of f is the reason f ∗ g {\displaystyle f * g } and f ⋆ g {\displaystyle f \star g } are identical in this example.

The symbol ~ is the tilde.The relation is an equivalence relation on the set of functions of x; the functions f and g are said to be asymptotically equivalent .The domain of f and g can be any set for which the limit is defined: e. g . real numbers complex numbers positive integers.. The same notation is also used for other ways of passing to a limit: e. g . x → 0 x ↓ 0 |x| → 0.

Since the norm function is not defined for the zero element of the ring we consider the degree of the polynomial f ( x ) = 0 to also be und…
