Please draw dynamic response for B & C

An input function is called doublet pulse as shown in the figure.

$($a$)$ Find the Laplace transform of this function

$($b$)$ What is the response of a process having a first$-$order transfer function $\frac{K}{s+1}$ to this

input? Draw the dynamic response.

$($c$)$ What is the response of an integrating process $\frac{K}{s}$ to this input? Draw the dynamic response.
