f(x) = ()–x
f(x) = ()x

Answer 1

The curve through the ordered pairs (0, 10), (1, 5), and (2, 2.5) can be represented by the function f(x) = 10(0.5)x. What is the multiplicative rate of change of the function?

0.5
2
2.5
5

Answer 2

0.4
0.6
1.5
2.5

Answer 3

1.5 ithink

Answer 4

\[y=ab^x \]
is exponential decay if a >0 and b is between 0 and 1
