WebNov 10, 2024 · In this section, we look at how to use derivatives to find the largest and smallest values for a function. Absolute Extrema Consider the function f(x) = x2 + 1 over the interval ( − ∞, ∞). As x → ± ∞, f(x) → ∞. Therefore, the …
WebThe function in this video is actually z, z (x,y). Unless you're dealing with f (x,y,z), a 4D graph, then no the partial of z would not be infinity. At maxima points (in 3D, z (x,y)), the partial of z would actually probably be 0 because the partials of x and y are 0 at these points. If you have almost no change in x or y, you would have almost ...
