WebInflection points are where the first derivative has relative max/mins (where the slope of the tangent line of the first derivative =0). He could have used the first derivative but not easily if he did it analytically. You can find points of inflection by looking at the graph of the first derivative, or by solving the 2nd derivative.

WebFor example, imagine we wanted to sketch the graph of the cubic function 𝑓 ( 𝑥) = ( 𝑥 − 2) ( 𝑥 + 1) . We can see that the function only has two roots, so there are only two 𝑥 -intercepts of its graph. These are at 𝑥 = − 1 and 𝑥 = 2. We can find its 𝑦 -intercept by evaluating 𝑓 ( 0). We have 𝑓 ( 0) = ( 0 − 2) ( 0 + 1) = − 2. philip heseltine composer

WebThe general form of a cubic function is y = ax 3 + bx + cx + d where a , b, c and d are real numbers and a is not zero. We can graph cubic functions by plotting points. Example: Draw the graph of y = x 3 + 3 for –3 ≤ x ≤ 3. Use your graph to find a) the value of y when x = 2.5 b) the value of x when y = –15 Solution: a) When x = 2.5, y ≈ 18.6 WebThus to draw the function, if we have the general picture of the graph in our head, all we need to know is the x-y coordinates of a couple squares (such as (2, 4)) and then we can …
