Best ResponseYou've already chosen the best response.31 ... but yes what is the value of the first derivative at x=1 to determine slope at x=1

Best ResponseYou've already chosen the best response.3right, and when x=1 we get? 3 right?

Best ResponseYou've already chosen the best response.0Wait, second derivative is zero is not sufficient for point of inflection. One also needs the lowestorder nonzero derivative to be of odd order.

Best ResponseYou've already chosen the best response.3slope at x=1 is 3; we need to know the value of y at 1 to determine a point for this:

Best ResponseYou've already chosen the best response.3what is the value of y when x=1? y = x^3 +3x^2 + 2, when x=1

Best ResponseYou've already chosen the best response.34? (1,4) so, the equation of the tangent at the inflection is putting all the parts together: tanY = 3x+3(1)+4
