The function f(t), that represents the number of members at the beach club as a function of the temperature is f(t) = 10t + 50
<u>Solution:</u>
Given that, When it was 70 degrees outside, 50 members showed up at a beach club.
For each degree the temperature rose, another 10 members came to the beach club.
We have to write the function, f(t), that represents the number of members at the beach club as a function of the temperature.
Now, according to the given information,
Initially 50 members and then, members keep on adding by rise in temperature,
So, 50 + t x 10 [ t represents change in temperature, and 10 is number of people who joins club
]
Then, f(t) = 10t + 50.
Hence, the function is f(t) = 10t + 50
