The discussion centers on calculating the differential and linear approximation for the function f(x) = x^(3/2) at x = 4 with a delta x (dx) of 0.1. The user initially calculated dy as 0.4 but received feedback indicating this result is incorrect. Clarification was sought regarding the function's notation, specifically whether it is interpreted as x√x or (x^3)/2, which is crucial for accurate calculations.

I got 0.4 for dy but its wrong, and i can't find deltay. please help! thxs
