Problem 9.2. Let f(x, y, z) = 5x + y - 3z. Determine whether f(x, y,z) has absolute extrema on the
intersection of the plane x + y + z = 0 and the sphere x2 + y² + z2 = 1. If the extrema exist, find them.

1^3 + 2^3 + 3^3 +4^3 = (1+2+3+4)^2

step-by-step explanation:

i am only able to answer the first part. i am not sure about the second part. sorry

sample answer: you can determine whether each element of the domain is paired with exactly one element of the range. for example, if given a graph, you could use the vertical line test; if a vertical line intersects the graph more than once, then the relation that the graph represents is not a function.
