1 answer

To interpret the equation \( T(x) = 2x + 10 \), where \( x \) is the number of hours after noon, we can find the initial value by evaluating the temperature at \( x = 0 \) (which represents noon).

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

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

The initial value (the temperature at noon) is \( 10°C \).

So the correct response is:

10°C
