Best ResponseYou've already chosen the best response.2Following mukushla's hint \[\large y=\dfrac{15x^2+2x+1}{x^22x1}\] cross multiplying and rearranging gives \[\large (15y)\color{red}{x^2}+(2+2y)\color{red}{x}+y+1 = 0\] This is a quadratic in \(\color{red}{x}\) you may use the discriminant to find the domain

Best ResponseYou've already chosen the best response.0The directions could be more clear. This might be better. "What integer values does the expression not attain. " or "What integer values does the function not attain. "
