y = expx
is plotted in the
x
interval [−3,2] .
Any exponential
function with
base a can be
expressed as
exponent: ax = exp( x ln a ).
For example a = 2 will
result in 2x = exp(x')
where
x' = x ln(2) ≅
0.693x .
Next the
scaling of x will
be animated.
After scaling the abscissa, the
plot represents y = 2 x , as well
as y = expx , depending on
the
choice of the abscissa.
Observe and verify the drawn
points of y = 2 x !
