Hey, it's clear. So when you read here is so we have f of X is equal to I need to the ex minus X cubed We could differentiate when we get beat to the ex minus three X square And to get our second derivative, we just differentiate first we gotta eat the X minus six x We're gonna draw our graph up with them all together at once. So original function enough of X while doing black and I'll look like this are derivative is in red and our second derivative is in green.
