Outside the integral when X equals zero, use equals zero next sequence and u is equal to and over Richie. Times take one over blue team high outside the bracket at Sorry. This is in school from zero end one over routine pie e minus 1/2 x squared the X Now that's introduces substitution let you be equals X over, route to and it's gonna be too. The X we know straight away that affects is even to be right. Okay, copy rescue evaluate into grew between minus end on end of after tax.
Then we've got downward slope here and I guess it up with slow on this side with increasing X.
WHAT IS CDF IN PROBABILITY PLUS
So we have a an inflection point here where it's flat on, Uh, plus or minus. Now we just reflect that around the, uh, the Y axis Onda. So it's gonna be monos honestly decreasing like this. Wells it's gonna flying off towards the end at the ingredient is always negative for X grins in road. Uh, on the greedy it is gonna be zero when x is really, really large than greatness. And they were reflected around the y axis because, uh, because the function is even okay when X is equal to zero, then f of x is gonna be one over real high. Uh, this guy is gonna because they were negative, depending on whether X is posted an exit. Okay, so this guy's always going to be positive. This, too is gonna cancel, uh, with the to that's gonna come down from the X rays having X repeats the minus, uh, X squared. That's the only offensive X on DTI to get an idea of the slope we could find if Andrews arrest with talked to ex, which is gonna bay minus 1/2. We can also see that is even function because ah, off this x squared term. That's because, Peter, any powerless, any real power is gonna be greater than zero. So let's just think about some properties of this book before we can draw it. So, given a normal distribution, uh, density function, whatever in here, where the mean is zero and stand deviation is one of a arrested draw the graph dysfunction s. In this video, we're gonna go through the answer to question number 85 which up to 8.7.
