1what is the first number you look at for this point? (1,6,7)
- A6
- B1
- C7
2On a countur plan red means very low values
- ATrue
- BFalse
3choose all of the choices that are multivarible funtions
- Aparabolas
- Bvector feilds
- Ccontur graphs
- Dsurfaces
4Vector Feilds can be also fluid motion
- ATrue
- BFalse
5which is a multivarible function?
- Af(x) = x^2
- Bf(x,y,z) xyz + cosx
- Cf(y) = y ^2
- Df(z) = z + 2
6A countur graph is what
- Aa three d graph
- Ba three d graph that is put on a two d graph
7There are many types of ways you can visualize multivariable functions. A point is represent by the [blank_start]x[blank_end] coordinate first. Then the [blank_start]y[blank_end] coordinate and last the [blank_start]z[blank_end] coordinate. A three-d graph is a [blank_start]surface[blank_end] that has depth, length, and width. You could represent a three-d graph as a [blank_start]counter plot[blank_end] which puts it on a two d plan. You can interpret a three-d graph by [blank_start]slicing[blank_end] it up in the different plans
- Ax
- Bw
- Cy
- Da
- Ez
- Fb
- Gsurface
- Hline
- Icounter plot
- Jvector field
- Kslicing
- Ldicing
8When you cut the graph cosing 3-d graph using slices the slice of y = 0 will get us a straight line.
- ATrue
- BFalse
9Which color represents the lowest points on a contur graph?
- Ared
- Bblue
- Corange
- Dyellow
10order the points from highest value to lowest value
- A1
- B2
- C3
- D4
- E5
- F6
- G7
11Red vectors are the shortest of the colors
- ATrue
- BFalse
12which vector means the smallest
- Ared
- Bblue
- Cyellow
13what is a another word for a donut?
- AA torus
- Ba halo
- Ca ring
14Select all of the true statements involving vector fields
- AWhen drawing vector fields draw the whole vector
- BWhen drawing vector feilds draw the vectors all of the same size.
- CYou can color code the vectors to represent length
15where will this vector start? f(x,y) = cosine(x) f(x,y) = ysin(x) f(x,y) = cosine(x)sin(y) (0,pi)
- A(1,0,0.5)

17When you tranform the input to a output which is a turos, the input is a square.
- ATrue
- BFalse
18Drag the input point to the proper output point. function f(x,y) = x + y and f(x,y) 2x - 3y
- A(1,1)
- B(-1,1)

- A(4,8)
- B(-4,8)
20find the outpput point f(x,y) = 2x + 2y f(x,y) = 2(x + 2y) , f(x,y) 2(x)^y point (3,2)
- A(10,14,18)
- B(11,14,18)
