Question
Find $f^{\prime}(0)$ and $f^{\prime}(1).$$$f(x)=\frac{a x^{2}+b x+c}{c x^{2}+b x+a} ; \quad a, b, c \text { constant. }$$
Step 1
The quotient rule states that the derivative of $\frac{u}{v}$ is $\frac{vu' - uv'}{v^2}$, where $u$ and $v$ are functions of $x$, and $u'$ and $v'$ are their respective derivatives. Here, $u(x) = ax^2 + bx + c$ and $v(x) = cx^2 + bx + a$. Show more…
