Which of the following could be the graph of a function? check all that apply
a. a line
e. a parabola

Both A. A Line and E. A Parabola

Step-by-step explanation:

Great question, it is always good to ask away and get rid of any doubts that you may be having.

Both A. A Line and E. A Parabola can be a graph of a function. Each is a representation of a different type of function.

A Line is a representation of a linear function. An example of a linear function would be the following,

A Parabola is usually a representation of a quadratic function or a function with the variable raised to an even exponent.  Which usually means each y-value has 2 x-values. An example of a function that graphs into a parabola is the following,

Both of these functions are attached below with their respective graphs

I hope this answered your question. If you have any more questions feel free to ask away at .

the value of v.w= -12.

step-by-step explanation:

we are given three vector r,v and w as:

r = < 5, -5, -2> ; v = < 2, -8, -8> ; w = < -2, 6, -5>

we know that r,v and w could also be represented as:

r=5i-5j-2k

v=2i-8j-8k

and w= -2i+6j-5k

where i,j and k are the unit vectors of x,y and z-axis respectively.

also we know that it has the following property:

i.i=1 ; j.j=1; k.k=1

and i.=j.i=i.k=k.i=j.k=k.j=0

i.e. when we multiply two vectors or we find it's dot product we need to only multiply the components of x coordinates with each other; y with each other and z with each other.

hence, v.w= (2i-8j- -2i+6j-5k)

                  = 2×(-2)+(-8)×(6)+(-8)×(-5)

                  = -4-48+40

                  = -12

hence, v.w= -12
