Gap-fill

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

A curve is defined by a function $y=\simplify{{x2}x^2 + {x1}x + {const}}$ .

What is the $y$ coordinate value of the point on the curve at $x=\var{n+2}$ ?

$y =$ Unnamed gap

Advice

When inserting numbers into your calculator make sure you place brackets correctly.

a)

As $x = \var{n+2}$,

substitute $\var{n+2}$ into $\var{x2}x^2 + \var{x1}x + \var{const}$.

\begin{align}
\var{x2}x^2 + \var{x1}x + \var{const} &= \var{x2} (\var{n+2})^2 + \var{x1}(\var{n+2}) + \var{const} \\
&= \simplify{{x2} ({n+2})^2 + {x1}({n+2}) + {const}}\,.
\end{align}

As $y = \var{n}$,

substitute $\var{n}$ into $\var{n+1}y^2-\var{x2}y$.

\begin{align}
\var{n+1}y^2-\var{x2}y &= \var{n+1}(\var{n})^2-\var{x2}(\var{n}) \\
&= \simplify{{n+1}({n})^2-{x2}({n})}\,.
\end{align}

As we are given a temperature in degrees Celcius, $T_C = \var{T_C}°C.$

Substituting $T_C$ into $T_C = 1.8\,T_C + 32$.

\begin{align}
T_F &=1.8\, T_C+32 \\
&=1.8 (\var{T_C}) + 32 \\
&= \var{dpformat(1.8 {T_C} +32, 1)}\,°F\,.
\end{align}
