Answer 1

To find the initial value from the equation that describes the temperature in degrees Celsius as a function of hours after noon, we can evaluate the equation at \( x = 0 \), which represents noon.

The equation given is:

\[
\text{Temperature} = 2x + 10
\]

Substituting \( x = 0 \):

\[
\text{Temperature} = 2(0) + 10 = 0 + 10 = 10
\]

Thus, the initial temperature (at noon) is **10°C**.

So the correct response is **10°C**.
