Problem 1 (Signal Transformation) (a) Find a transformation of the type $y(t) = x(at - b)$ that connects $x(t) = 4t$ to $y(t) = 2(t + 4)$. (b) In the following figure we plot the signal $y(t)$. It is known that $y(t)$ is obtained from the original signal $x(t)$ by the following transformation $y(t) = \frac{1}{5}x(-2t - 3)$. Determine and sketch the original signal $x(t)$.
