For what values of the constant k does the Second Derivative Test guarantee that f (x comma y )equalsx squared plus kxy plus y squaredwill have a saddle point at (0 comma 0 )​?A local minimum at (0 comma 0 )​?For what values of k is the Second Derivative Test​ inconclusive? Give reasons for your answers.

i don't know, but that looks pretty bad. my school passed us unless we failed in all the subjects, but idk abt ur school's rules.

8.75

how-to:

first, we need to find what we have to work with.

since i know that we have 7 (years) and 0.8 (inches), we can use these to solve and find the equation!

secondly, what you want to do, is see that we need to know how much growth out of the 0.8 inches he got in only 1 year, instead of 7 years.

let's try to divide.

7 ÷ 0.8 = 8.75
