2°C

Answer 1

To find the initial value of the temperature equation \( T(x) = 2x + 10 \), we need to evaluate the equation at the point where \( x = 0 \) (which corresponds to noon).

Substituting \( x = 0 \) into the equation:

\[
T(0) = 2(0) + 10 = 0 + 10 = 10°C
\]

So, the initial value of the temperature at noon is **10°C**.
