A defining property of
e
x
is that it equals its own derivative:
d
x
d
e
x
=
e
x
. Why is this property important?
Hide and think first
A.
It makes
e
x
computable by a polynomial of degree 1, which simplifies numerical calculations on hardware
B.
It makes
e
x
the unique function (up to a scalar) satisfying
f
′
(
x
)
=
f
(
x
)
, which models exponential growth and decay processes
C.
It implies that
e
x
=
1
+
x
for small
x
, which is the first-order Taylor approximation used in numerical methods
D.
It guarantees that
e
x
is monotonically increasing for all
x
∈
R
, which follows trivially from the derivative identity
