Gap-fill

Ask the student a question, and give any hints about how they should answer this part.

$f(x) = \simplify{ {a}*x^{b} + {c}/(x^{d}) + {ee}}$

Gradient at $x=\var{g}\;$ is Unnamed gap

Input your answer to 3 decimal places.

Advice

We have

$\frac{df}{dx}=\var{a*b}x^{\var{b-1}}-\var{c*d}x^{\var{-d-1}}$

The gradient at $x=\var{g}$ is given by the value of $\displaystyle \frac{df}{dx}$ at $x=\var{g}$ and we therefore have:

Gradient = $\var{a*b}\times(\var{g})^{\var{b-1}}-\var{c*d}\times (\var{g})^{\var{-d-1}}= \var{dpformat(ans1,3)}$ to 3 decimal places.
