Your answer in the line above should be in terms of both xx and hh

So$,$ the numerator of our rational expression becomes f$($x$+$h$)$f$($x$)=(($f$($x$+$h$)$f$($x$)=((992$x$2+12$x$2+1)()(992($x$+$h$)2+12($x$+$h$)2+1))))/(((2($x$+$h$)2+1)(2$x$2+1)(2($x$+$h$)2+1)(2$x$2+1))=)=$

Marks for this submission: $0\mathrm{.}00/1\mathrm{.}00.$

Hint: you do not need to worry about expanding the denominator of this expression

Your answer in the line above should be in terms of both xx and hh

So$,$ now we need to find f$($x$)=$limh$0($f$($x$)=$limh$0(/$ h$)=$h$)=$ By cancelling out the common factor between the numerator and denominator

Your answer in the line above should be in terms of both xx and hh

Evaluating the limit$,$ we find that f$($x$)=$limh$0($f$($x$)=$limh$0()=)=$

Your answer in the line above should be in terms of xx only

So$,$ the function f$($x$)$f$($x$)$ is f$($x$)=$
