Answer 1

To find the initial value in the given equation \( T(x) = 2x + 10 \), we need to determine the temperature at the time zero hours after noon, which corresponds to \( x = 0 \).

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

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

Therefore, the initial value, which is the temperature at noon, is \( 10°C \).

The correct response is:

10°C
