Step-by-step explanation:
The answer is 48 because you have to do is 21 x 4 which is 48
Using an exponential function, it is found that f(5.5) = 19.8.
<h3>What is an exponential function?</h3>
An exponential function is a function in which the growth rate is a percentage, modeled by:
In which:
f(3.5) = 25 means that:
f(8.5) = 14 means that:
Hence:
Hence, the function is given by:
Then, when x = 5.5:
