A large square has an area of $1,296$ square centimeters (${\text{cm}}^2$). Small squares of area $36{\text{ cm}}^2$ are cut out of the large square one by one. Which function $f$ gives the area of the resulting figure, in ${\text{cm}}^2$, after $x$ small squares are cut out?

A

$f(x)=1,296-36x$

B

$f(x)=1,332x$

C

$f(x)=1,296x-6$

D

$f(x)=1,290x$
