Let y=3x2+2x+2.
Find the differential dy when x=5 and dx=0.1
Find the differential dy when x=5 and dx=0.2
First, you need to find the derivative of the given quadratic function. Then, evaluate this derivative at the given x-value. Finally, multiply the result by the given dx value. Remember, the differential represents the approximate change in y for a small change in x.
