Is an exponential decay function represent a quantity that has a constant halving time?

A quantity is said to be subject to exponential decay if it decreases at a rate proportional to its value. The time required for the decaying quantity to fall to one half of its initial value.
Radioactive decay is a good example where the half life is constant over the entire decay time.
In non-exponential decay, half life is not constant.

An exponential growth function represents a quantity that has a constant doubling time?
True
An exponential function is written as Fx equals a bx where the coefficient a is a constant the base b is but not equal to 1 and the exponent x is any number?
positive
An exponential decay function represents a quantity that has a decreasing halving time?
exponential decay doesnt have to have a decreasing halving time. it just decays at a certain percentage every time, which might be 50% or might not

Explain the exponential function with the help of an example?
The exponential function describes a quantity that grows or decays at a constant proportional rate. It is typically written as f(x) = a^x, where 'a' is the base and 'x' is the exponent. For example, if we have f(x) = 2^x, each time x increases by 1, the function doubles, showing exponential growth.
What does the constant represent in an equation?
It represents a fixed quantity.
Constant is a quantity that does not?
Constant is a quantity that does not change.

Why only half quantity of atoms undergo decay?
nuclear decay is a simple random process, the more of something there is the more of it will decay if the probability of decay is constant (which it is).the simplest way to quantify this is halflife, as you mention. but there is nothing special about halves, it can also be specified by the decay constant k that appears in the exponential decay function: n = n0 e-kt where n0 is initial quantity, n is current quantity, and t is time since initial time. or you could choose to specify it in thirdlife, quarterlife, fifthlife, hexadecilife, centlife, or whatever... but nobody else does.
