Find the domain of the following functionsf(x, y)-25-x2 -y – InterviewSolution

1.

Find the domain of the following functionsf(x, y)-25-x2 -y

Answer»

for domain the term under the root should always be > 0

so, 25 -x² -y² > 0=> x²+y² < 25

so, this is an equation of circle having radius 5 units and all the points lying inside it.. will be in the domain

from x = -5 to 5 and. y = -5 to 5
