we have that
y = 2(0.45)^x
in this problem
2-----------> is the Coefficient
0.45-------> is the Base
x-----------> is the Exponent
we know that
If
the base is less than 1 (but always greater than 0), the function will be
exponential decay
It is decay because as x values
increase, y values decrease.
0.45 < 1 and 0.45 > 0
therefore
the equation
y = 2(0.45)^x
represents exponential
decay
the answer is
exponential decay
