Hello, confusedagain!

Still unsure of how to find the inflection points with an e^x problem...

Take this problem:

?

The derivative of: . is: .

In baby-talk: the exponential function itself times the derivative of the exponent.

If

. . then: .

. . then: .

To find inflection points, solve

So we have: .

. . Divide by -0.0009: .

. . Multiply both sides by .. . . What?

Therefore, there arenoinflection points.
