Answer

Explanation:

Step1: Analyze the graph

We need to find the $x$ - values when $f(x)$ (temperature) is between the initial value and 45°C.

Step2: Locate 45°C on the graph

By looking at the graph of $y = f(x)$ (temperature vs time), we find the $x$ - value corresponding to $y = 45$.

Step3: Determine the interval

The experiment starts at $x = 0$ and stops when the temperature reaches 45°C. From the graph, when $f(x)=45$, $x\approx6$. The experiment starts at $x = 0$ and ends when $x = 6$. So the interval is $0\leq x\leq6$.

Answer:

A. $0\leq x\leq6$
