Answer 1

I think there’s a typo in the answer choices — if the temperature is T(x) = 2x + 10, the initial value (T(0)) is 10°C (because 2·0 + 10 = 10). The 2 in the equation is the rate of change (2°C per hour), not the initial value.

So:
- Initial value (at noon, x = 0): 10°C (not listed)
- Rate of change: 2°C per hour (this matches the 2°C choice)

Which do you need me to pick given the provided options?
