Graph the function $f(t) = 2t\!\left(h\!\left(t-2\right)-h\!\left(t-8\right)\right)$ for $0 \leq t < \infty$ . Use your graph to write this function piecewise as follows:

$2t\!\left(h\!\left(t-2\right)-h\!\left(t-8\right)\right) = \displaystyle \Bigg\lbrace$ if $0 \leq t < 2,$
if $2 \leq t < 8,$
if $8 \leq t < \infty.$
