Q1: Consider the function $f: \mathbb{R} \rightarrow \mathbb{R}$ given by $f(x) = x^2$. Which claim is not correct?
A1: $f|_{[a,b]}$ is Riemann-integrable for all $a \leq b$.
A2: $\int_a^b f(x) , dx $ is well-defined for all $a \leq b$.
A3: $ \int_0^\infty f(x) , dx$ converges.
Q2: What is the integral $ \int_{-\infty}^{0} \exp(x) , dx$
A1: $-1$
A2: $1$
A3: $-\pi$
A4: $\pi$
A5: $\frac{1}{2}$
A6: $-\frac{1}{2}$
Q3: What is the limit $$ \lim_{c \rightarrow \infty} \int_{-c}^{c} x , dx$$
A1: Not defined!
A2: $\infty$
A3: $-\infty$
A4: $0$
Q4: Does the improper Riemann integral $$ \int_{-\infty}^{\infty} x , dx$$ exist?
A1: No!
A2: Yes!
A3: The notation $\int_{-\infty}^{\infty}$ never makes sense.
