Points, Vectors, and Functions

Example 1

Define the function f by f(x,y,z) = x + - z. Then f:ℜ3→ℜ. Find 

  •  f(2,-4,5)

Example 2

Define the function f by f(x,y,z) = x + - z. Then f:ℜ3→ℜ. Find 

  • f(2,4,-5)

Example 3

Define the function f by f(x,y,z) = x + - z. Then f:ℜ3→ℜ. Find 

  • f(1,1,1)

Example 4

Determine if each equation describes a vector function or a scalar function.

Example 5

Determine if each equation describes a vector function or a scalar function.

  • f(x,y) = (y,x)

Example 6

Determine if each equation describes a vector function or a scalar function.

  • f(x,y) = y - x

Example 7

Determine if each equation describes a vector function or a scalar function.

  • f(x,y) = y2

Example 8

Determine if each equation describes a vector function or a scalar function.

  • f(x,y) = (x + y, x2 + y2)
