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
