Explain how the sign of the first derivative affects the shape of a function s graph State the first derivative test for critical points Use concavity and inflection points to explain how the sign of the second derivative affects the The derivative is y 15x2 4x 3 The second derivative is y 30x 4 And 30x 4 is negative up to x 4 30 2 15 positive from there onwards So f x is concave downward up to x 2 15 f x is concave upward from x 2 15

If we are trying to understand the shape of the graph of a function knowing where it is concave up and concave down helps us to get a more accurate picture Of particular The point where the function is neither concave nor convex is known as inflection point or the point of inflection In this article the concept and meaning of inflection point how to determine the inflection point graphically
Inflection points are points where the first derivative changes from increasing to decreasing or vice versa Equivalently we can view them as local minimums maximums of f x Wiki page This section is on how to find inflection points First of all find the first derivative of a function Then proceed to finding the second derivative of a function
