Questions and Answers

Which set denotes the vector space of all linear transformations from V to W?

  • V ∗
  • L(V, W) (correct)
  • W ∗
  • L(V)

What is the formula for (f + g)(v)?

  • (f + g)(v) = f(v) - g(v)
  • (f + g)(v) = f(v) + g(v) (correct)
  • (f + g)(v) = f(v) / g(v)
  • (f + g)(v) = f(v) * g(v)

What is the formula for (k · f)(v)?

  • (k · f)(v) = k - f(v)
  • (k · f)(v) = k + f(v)
  • (k · f)(v) = k * f(v)
  • (k · f)(v) = k · f(v) (correct)
