Answer:
Step-by-step explanation:
"F" is the name of a function. If we choose "60" as the input to this function, the resulting output vaue is 86. The function F maps 60 (input) onto 86 (output).
check the superb reply above, however to the risk of sounding redundant.
[tex]\bf f(\stackrel{\stackrel{in put}{x}}{60})=\stackrel{\stackrel{ou tput}{f(x)}}{86}~\hspace{8em} \stackrel{x}{in put}\textit{ of 60, will yield an }\stackrel{f(x)}{out put}\textit{ of 86}[/tex]
