Which is an exponential decay function? O fm =3(5)
O $
(x) =} (*)*
o flw=109
O 1 =(-3)

In mathematics, exponential decay describes the process of reducing an amount by a consistent percentage rate over a period of time. It can be expressed by the formula y=a(1-b)x wherein y is the final amount, a is the original amount, b is the decay factor, and x is the amount of time that has passed.

Step-by-step explanation:

the formula of a slope:

from a table we have

substitute:

the slope of f(x) is -1.

the graph of funcfion g(x) is a horizontal line. the slope of a horizontal line is equal 0. therefore the slope of g(x) is 0.

-1 < 0

80x^8−68x^6+16^5−20x^4−4x^3+8x^2

hope i'm right lol
