7. (a) Graph the function f(x) = VT- x².
(b) Graph the function f(x, y) = /1– x² – y². (Hint: Let
z = /1-x2 - y?, and then square both sides of the
equation.)
(c) The graph of the function
f(x, y, z) = /1 – x² – y2 – z4
is half of a hypersphere of dimension 3. Explain why
"hypersphere" is a good name for the graph and why
the graph is only half of the hypersphere. What equa-
tion defines the entire hypersphere?
