ive got a quiz tomorrow, and this is one of the example questions

i have looked through my text and my notes, and havent found anything that could help me.

Suppose that is a smooth function and that its partial derivatives have the values, and . Given that , use this information to estimate the following values:

Estimate of (integer value)

Estimate of (integer value)

Estimate of (integer value)

at first I was trying to come up with a function that would satisfy that derivatives and the function, but it turned out to be harder than i thought. what do i need to do?
