[tex]\bf \underline{ \underline{Given : }}[/tex]
f(x) =x + 3/2
[tex]\bf \underline{ \underline{To \: be \: calculated : }}[/tex]
what is the value of f(-1) ?
[tex] \bf \underline{ \underline{Solution : }}[/tex]
[tex] \sf{f(x) = x + \dfrac{3}{2} }[/tex]
[tex] \rightarrow \sf {f( - 1) = ( - 1) + \dfrac{3}{2} }[/tex]
[tex] \rightarrow \sf{f( - 1) = \dfrac{ - 2 + 3}{2} }[/tex]
[tex] \rightarrow \sf{f( - 1) = \dfrac{ 1}{2} }[/tex]
[tex] \rightarrow \sf {f( - 1) = 0.5}[/tex]
