f(x)=\dfrac{3x^2+4x+18}{x^2-ax+11}

In the rational function above, a is a constant. The function is defined for all but two values of x. If one of the values of x for which the function is undefined is 1, what is the value of a ?

I think there may be a typo- seems like it should read “The function is defined for all values of x except two.” instead of “The function is undefined for all values of x except two.”
