Where m(v) is mass of body when it moves with speed v in relation to observer,m0 is the mass of body at rest in relation to observer(ie a constant for example 1 kg)and c is speed of light

(1) domain and range of m(v)

(2)when velocity is 0 what is the mass?(this is vertical intercept)

(3)determine equation of vertical and horizontal aymptotes

(where is m(v) increasing and decreasing.

(4) where is m(v) concave up and down
