Suppose f:double-struck Rn ā double-struck Rm and g:double-struck Rp ā double-struck Rq. (a) What must be true about the numbers n, m, p, and q for f ā g to make sense? n = q m = p n = p m = q n = m (b) What must be true about the numbers n, m, p, and q for g ā f to make sense? n = q m = p n = p m = q n = m (c) When does f ā f make sense?
