Write an exponential function for the set of points

Mathematics
1 answer:
mart [117]3 years ago
6 0

Answer:

The function is f(x) = 27(\frac{1}{3})^x

Step-by-step explanation:

Compare the y values. Notice that the y values are all multiples of 3 and they decrease by dividing by 3 each time. This suggests the base is 1/3.

Now check when x = 0. This is the initial value since the zero exponent gives an output of 1. So the only way for (0,27) to be a point is for 27 to e multiplied as the initial value. The function is f(x) = 27(\frac{1}{3})^x
