x+1/absx+2

could you explain it please? thankyou!

you could try something like
\[f(x)=\frac{x}{x^2+1}\]

the first response isn't a rational function. They have to be polynomials.

oh what @scarydoor said

@satellite73 's hint is on the money... easy to convert that to the right function.

@scarydoor how can i convert it to the right function? i dont understand

\[f(x)=\frac{ x+1 }{ x^2+1 }\]
can anyone confirm this answer? i think its right...

ahh thankyou! yes it makes sense
