Let y = 5*sqrt(x),
1) Find the change in y, delta y when x =3 and delta x = 0.2
2) Find the differential dy when x = 3 and dx = 0.2
I found the answer for #2 just fine by deriving the function, finally giving me (5/2)*(3)^(-1/2)*(0.2). I'm not sure what to do for #1, though.

1 asks you to find y(3.2) - y(3)...and then #2 will show how ' close ' the answers are
