B, because the first graph shows a rate of 35 mph. We don’t want that. Answer c states, that the rate is constant however that is not true. B is the only equation showing that if you plug in any x for the number of hours, you will get your answer. Therefore b is your answer! Hope this helps

Answer:
The y-intercept is (0,210)
Step-by-step explanation:
We have the function, ![f(x)=201+9e^{3x}](https://tex.z-dn.net/?f=f%28x%29%3D201%2B9e%5E%7B3x%7D)
So, we know that,
<em>'y-intercept is the point on the graph where the function crosses y-axis'.</em>
i.e. y-intercept is obtained when x=0.
Thus, substituting x=0 in the given function, we get,
![f(0)=201+9e^{3\times 0}](https://tex.z-dn.net/?f=f%280%29%3D201%2B9e%5E%7B3%5Ctimes%200%7D)
i.e. ![f(0)=201+9e^{0}](https://tex.z-dn.net/?f=f%280%29%3D201%2B9e%5E%7B0%7D)
i.e. ![f(0)=201+9\times 1](https://tex.z-dn.net/?f=f%280%29%3D201%2B9%5Ctimes%201)
i.e. ![f(0)=201+9](https://tex.z-dn.net/?f=f%280%29%3D201%2B9)
i.e. f(0) = 210
Also, we can see from the given graph that the function crosses y-axis at (0,210).
Hence, the y-intercept is (0,210).
