During nuclear explosion, one of the products is \( ^{90} \) Sr with half life of 28.1 yr. If \( 1 \mu g \) of \( ^{90} S r \) was absorbed in the
bones of a newly born baby instead of calcium, how much of it will remain
after 10 year and 60 year if it is not lost metabolically.

ff \( f, g: R \rightarrow R \) be two functions defined
as \( \boldsymbol{f}(\boldsymbol{x})=|\boldsymbol{x}|+\boldsymbol{x} \) and \( \boldsymbol{g}(\boldsymbol{x})=|\boldsymbol{x}|-\boldsymbol{x} \) for
all \( x \in R \). Then, find \( f \circ g \) and \( g \circ f \) Hence, find \( \boldsymbol{f} \circ \boldsymbol{g}(-\boldsymbol{3}), \boldsymbol{f} \circ \boldsymbol{g}(\boldsymbol{5}) \) and \( \boldsymbol{g} \)
\( \boldsymbol{f}(-2) \)
