Ingat aturan rantai ,misalkan sehingga maka Oleh karena itu, jawaban yang benar adalah E.

Ingat aturan rantai $fraction numerator straight d y over denominator straight d x end fraction equals fraction numerator straight d y over denominator straight d u end fraction times fraction numerator straight d u over denominator straight d x end fraction$ , misalkan u equals 3 minus 4 x sehingga y equals blank square root of u maka
