Gap-fill

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

Evaluate $f(\var{a3})$

$f(\var{a3})$ = Unnamed gap

Advice

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

$x=\var{a3}$

$f(\var{a3})=\var{a1}*(\var{a3})^{\var{a2}}+\var{b1}*(\var{a3})-\var{c1}$

$f(\var{a3})=\simplify{{a1}*{a3}^{{a2}}}+\simplify{{b1}*{a3}}-\var{c1}$

$f(\var{a3})=\simplify{{a1}*{a3}^{{a2}}+{b1}*{a3}-{c1}}$
