Question statement

Differentiate the function:

$f(x)=\var{a1}x^{\var{a2}}+\var{b1}x^{\var{b2}}+\var{c1}$

Give any introductory information the student needs.

Gap-fill

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

$\frac{df}{dx}=$ Unnamed gap

Advice

Apply the rule:

$y=ax^n\,\,\,then\,\,\,\frac{dy}{dx}=nax^{n-1}$

In this example

$f(x)=\var{a1}x^{\var{a2}}+\var{b1}x^{\var{b2}}+\var{c1}$

$\frac{df}{dx}=\var{a2}*\var{a1}x^{\var{a2}-1}+\var{b2}*\var{b1}x^{\var{b2}-1}$

$\frac{dy}{dx}=\simplify{{a2}*{a1}x^{{a2}-1}+{b2}*{b1}x^{{b2}-1}}$

Give a worked solution to the whole question.
