Hi, so when i interpret your question, it looks like you've got the function f of x is x squared plus 11.
00:10
The typing was a little bit weird in there, but i'm going to assume that's what you had.
00:14
And the question starts to ask about whether this function is increasing or decreasing.
00:19
So the way that we're going to do that is first find the first derivative.
00:23
The first derivative is where you do power rules.
00:26
You bring your power down and subtract one to the power.
00:28
The derivative of 11 is zero.
00:30
So here, if we would solve when our first derivative is zero, we're going to solve when zero equals 2x.
00:36
That's giving us when x equals zero.
00:39
And at x equals zero, this is called your point of inflection...
