The questions where asking to compute for the derivative of x->a, and base on my own calculation and further computation about the said function, the derivative of x->a is  \[f'(x)=-6x-5\] and if you replace x by 1 here you will get \[f'(1)=-11\]. I hope you are satisfied with my answer and feel free to ask for more
